[geda-gerbv.git] / ChangeLog_pre20080201

2008-01-29 23:30  thepurlieu
        * src/gerbv.c: cleanup help printout and change the format to
          better follow most other   programs.

2008-01-24 11:12  thepurlieu
        * src/draw.c: speed up cairo rendering of macros by checking each
          macro for any clear   draws, then only using push/pop group if we
          need to.

2008-01-23 22:23  thepurlieu
        * src/draw-gdk.c, src/draw-gdk.h, src/draw.c, src/export-rs274x.c,
          src/gerb_image.h, src/gerber.c, test/golden/example_jj_l1-2.png,
          test/golden/example_jj_l1-3.png,
          test/golden/example_jj_l1-orig.png,
          test/golden/test-polygon-fill-1.png: change polygon structure
          slightly and move "arc chopper" logic into the GDK   draw
          functions, and store only the arc info in the gerb_image struct.
          This   allows exporting with 100% accuracy, speeds up the cairo
          rendering, and reduces   the size of the gerb_image.  Update 4
          golden files as a result of this change, since the cairo renderer
          now   renders with the default resolution instead of the mandated
          1 degree resolution   with the previous method.  Add more
          functionality to the export code, including info headers,
          polarity   changes, and finishing the polygon stuff. The only
          major code that still needs   to be added is macro exporting.
          This may wait until (or if) we re-arrange the   macro storage
          method.  Change GDK renderer to use a double for the scale
          factor instead of an int. The int   was causing noticable error
          during rendering of large boards in comparison to   the cairo
          version (which was correct).

2008-01-23 19:49  thepurlieu
        * src/gerber.c: Fix bug 1878509 by adding a hack to assume linear
          interpolation is desired   if no I or J parameter is given. All
          other programs seem to assume this, so   it should be safe.
          Also, the testsuite still passes after this change, so   it
          shouldn't break anything.

2008-01-21 23:29  thepurlieu
        * src/export-rs274x.c: round values before writing to file in order
          to make sure no truncation errors are included.

2008-01-21 22:38  thepurlieu
        * src/: Makefile.am, export-rs274x.c, export-rs274x.h, gerbv.c:
          *export-rs274x.[ch]: start coding the library to export a
          gerb_image    to a Gerber file. Currently it supports basic
          aperture drawing and      polygon fills without circular paths
          inside them. This should support   most all files exported from
          PCB, though. For now, only the command     line option is hooked
          into this new library for testing (--export-rs274x).

2008-01-13 17:18  thepurlieu
        * src/: draw-gdk.h, interface.c:        fix bug #1870444 (and a
          similar report about problems on MAC compiling)
                    by allowing both draw.h and draw-gdk.h to be included.

2008-01-13 16:11  thepurlieu
        * test/golden/test-circular-interpolation-1.png:  Update
          golden circular interpolation file to reflect updated test file.

2008-01-13 16:09  thepurlieu
        * ChangeLog, src/gerbv.c, src/interface.c, src/render.c,
          test/inputs/test-circular-interpolation-1.gbx:
          Get short options working for export from commandline options
          Get exporting from command line working
          without the need for a display (cairo only). This was a regression
          after the late on-the-fly GDK code. Get background color to show up
          correctly on loaded projects.

---- Release 2.0.0 on 1.13.2008 ----
        
2008-01-12  Julian Lamb
        * draw.c: Fix a few minor cairo rendering issues: 1) fix rendering of
          circular interpolation within a polygon fill. 2) Fix rendering of
          flashed polygon apertures with holes in them.
        * tests: Add 8 new test files to test out aperture drawing, and 1 to test
          polygon fills.
        * tests/golden/*: Update all golden files in preparation for 2.0 release.
          20 tests were failing for a variety of reasons.  Most were due to the
          recent disabling of anti-aliasing on polygon fills, which caused very
          small changes to the rendering of the polygon borders. The remainder
          of the failings were due to spurious lines previously being drawn on
          flashed apertures with holes (noticed by Stefan), which has now been
          fixed.
        * draw.c: Fix small error in cairo rendering of elliptical circular
          interpolation paths.
        * test/input/test-circular-interpolation.gbx: added another test file.

2008-01-10  Julian Lamb
        * interface.c: Try and fix bug where tooltips weren't showing up for some
          users.
        * many files: Implement on-the-fly switching between GDK and cairo
          rendering, and set default setting on cairo builds to "Fast" (GDK).
        * draw.c: Fix spurious line rendering noticed by Stefan on BGA pads.
        * draw.c: Turn off anti-aliasing just on all polygon draws, since they were
          showing seams on ground planes.
        * draw.c: Fix clearing of BGA pin holes bug noticed by Stefan.
        * draw.c: Add "exposure off" logic, allowing macros with the exposure=off
          parameter to erase.

---- Release 2.0.0-beta ----

2008-01-09  Julian Lamb
        * gerbv.c: Make sure we increase max_files by 2, since we may need to
          open up two files for PNP layers (top + bottom). This fixes a segfault
          after adding a PNP file to the project and then clicking "New".

2008-01-08  Julian Lamb
        * callbacks.c: Change color dialog to "blocking", which prevents user
          from modifying layer orders while it is running and preventing
          possible problems with the layer tree code.

2008-01-07  Julian Lamb
        * interface.c, callbacks.c: Add in warning dialogs if user starts a new
          project or opens a project with existing layers to make sure they
          don't accidentally close all layers.
        * callbacks.c: Add in some logic to switch to inches in the rulers if the
          scale gets too small in mils.  Change the default unit back to mils.
        * interface.c: Recognize the default unit and start the unit combo box
          to the right one.
        * render.c: Change the default screen size scale factor to where mils
          can reasonably show up on the rulers.
        * draw.c: Revert back to old oval rendering for the time being, since the
          new one seems to be having issues...
        * gerbv.c, others: Add a dialog to confirm the user wants to open a file
          with invalid ASCII characters.
        * pick-and-place.c: Make sure we check cir_seg height and width are > 0,
          otherwise it can cause cairo rendering problems.
        * draw.c: Reduce label text font size, since the protel-pnp example file
          reveals problems fitting the text on the image.

2008-01-06  Julian Lamb
        * pick-and-place.c, gerbv.c: Render top and bottom layers in separate
          layers (if they exist). Rotate parts correctly and fix min/max 
          calculations so autoscaling works correctly. Also, add "top" and 
          "bottom" labels to layer names.
        * draw.c, draw-gdk.c, gerb_aperture.h: Add rendering code in preparation
          for aperture macro reordering.
        * render.c, callbacks.c: Add in watch cursor during rendering to provide
          feedback to user.
        * callbacks.c: Tweak the color dialog checks to make sure it works after
          destroying the dialog via the window manager. For cairo, speedup
          rendering during layer actions by simply recompositing the final image
          instead of redrawing everything. On layer deletion, reselect the first
          row to always make sure a line is active.
        * render.c: Reorder rendering so top layer is displayed on top.
        * callbacks.c, render.c: Get unit changing combobox to work more elegantly
          by updating all relevent fields immediately after changing units. Re-
          enable mils on the rulers, since inches were just too large to be
          usable for most boards.
        * interface.c: Get gui to gracefully shrink to a small size to support
          small screen resolutions. Prevent the sidebar from shrinking smaller
          than looks respectable. Change analysis tools to refer to "visible"
          layers rather than "active" layers to prevent confusion with the
          highlighted row in the layer tree. Add a frame around the statusbar to
          make it more visually appealing. Remove the "online manual" menu item
          since we don't actually have one yet.
        * draw.c: Change oval rendering to oblong, since that's probably what is
          actually intended (GDK rendering already did this).

2008-01-05  Julian Lamb
        * interface.c: Remove a billion glade-generated gtk_widget_show function
          calls, since they aren't needed with gtk_widget_show_all.
        * interface.c: Add tooltips for all menus and buttons.
        * interface.c: Update menus for new pointer tool and remove reference
          to control gerber option, since it's out for 2.0.
        * callbacks.c: Make middle mouse button the default pan tool, and update
          the mouse cursor is the user is panning or zooming with middle/right
          mouse buttons.
        * interface.c,callback.c: Add right click menu to the layer tree and add
          column to indicate any modifications to the layer (for now, we just
          show "I" for an inverted layer). Add back in support for individually
          inverted layers. Also, fix XOR and OR rendering modes for GDK.
        * render.c: Fix bug in alpha usage, which wasn't allowing transparency
          on exported images.
        * tests/golden/*: Update all golden files, since the png export wasn't
          using alpha correctly, so all test files now render with a slightly
          different color (since the black can bleed through the blue color
          a tiny bit).
        * gerber.c: Add support for include files (%IF) in the parser, which
          hopefully completes 100% implementation of the RS-274X spec (yay!).

2008-1-4  Stuart Brorson (sdb@cloud9.net)
        * src/callbacks.c, src/gerbv_screen.h, src/icons.h, 
        src/interface.c: Added pointer button to toggletools on task
        bar.
        
2008-01-04  Stefan Petersen  <spe>

        * src/interface.c: Changed menu entries where another window is popped
          up so text ends in three dots. "Save as" and "Print" uses built in
          GTK operations, so the hack there got not so nice. Is there other 
          ways, like predefined with the three dots?
        * src/draw-gdk.c: Fixed aperture macro drawing in GDK target as well.

2008-01-03  Julian Lamb
        * draw.c: Fix some amacro rendering problems that Stefan uncovered.
        * draw.c: Change the thermal rendering logic to do rendering without
          push/pop operations, so that vector output will work (previously, the
          cairo export defaulted to an image export for thermal rendering).
        * render.c: Fix autoscaling for new amacro test (although the hack will be
          unnecessary after we reorder the amacro rendering process to correctly
          calculate the extents of each flashed macro aperture).
          
2008-1-2  Stuart Brorson (sdb@cloud9.net)
        * src/Makefile.am, src/icons.h, src/interface.c:
        Added icons for toggletool buttons: move, zoom, and measure.

2007-12-31  Julian Lamb
        * gerbv.c: Rework project filename saving to save all layers with relative
          pathnames, relative to the project file location. This allows projects
          to be relocated, and fixes the second half of bug# 1443885.
        * gerbv.c: More work on command line parsing.
        * interface.c, render.c, callbacks.c: Reimplement different rendering modes
          into the sidepane combobox for GDK. For cairo, allow the user to change the
          quality vs speed.
        * pick-and-place.c, draw.c: Correct pick and place parsing to use inches
          for the basic unit. Render names of pick-and-place components to help
          check placement.
        
2007-12-31  Stuart Brorson (sdb@cloud9.net)
        * src/drill.[hc], gerber.[hc], gerbv.c, pick-and-place.[hc]:
        Overhauled checks for file type.  Now all file types (Gerber,
        drill, pick-place) are FALSE by default, and only are TRUE
        when positive of file type indications are found.  Also added
        specific check for RS-284-D, and throw error if -D is found.
        
2007-12-30  Julian Lamb
        * callbacks.[ch], interface.c, others: Implement three "tools", namely
          the pointer, zoom, and measure tool and hookup to the existing gui
          stubs. Also, display an informative message in the message bar explaining
          how to use the active tool (similar to Inkscape). Do some miscellaneous
          cleanups in the gui code and rendering.
        * callbacks.c, render.[ch]: Get basic printing support working.

2007-12-28  Stefan Petersen  <spe@spe-laptop>
        * src/draw.c, src/amacro.[hc]: gerbv can handle comments
          and calculations in aperture macros. Unfortunate this 
          uncovered some errors in how aperture macros are drawn.
          That will be next issue.

2007-12-28  Julian Lamb
        * gerber.c, many files: Finish implementing all remaining Gerber functions
          (offsets, mirrors, rotations, knockout, axis select, scale factors,
          and justify). Rework the min/max calculation routines for much more
          accurate autoscaling.  Also, much updating was needed to allow the new
          Gerber functions to autoscale correctly (e.g. scaling needs multiply all
          the min/max values by the image scale factor, etc).
        * tests/inputs/test-...: Add test files for all Gerber functions.
        * tests/golden/*: Update all the golden files, since the autoscaling
          rework made all the old golden files fail, since the scale factor is now
          slightly off from the previous ones, making them fail.

2007-12-28  Stuart Brorson (sdb@cloud9.net)
        * src/callbacks.c, src/drill.c, src/gerb_stats.[hc], src/gerber.c
        src/gerbv_screen.h, src/interface.c, src/pick-and-place.c:
        Added more checks for file type. This should fix problem
        of segfaults when reading RS-274D.  Make messages text window
        (in sidepane) pop up if an error or warning is written to it so
        user can immediately see problems.  Robustified a few areas
        of stats gathering code.        
        

2007-12-25  Stuart Brorson (sdb@cloud9.net)
        * src/gerber.c, src/callbacks.c, src/gerb_stats.[hc]:
        Added reporting of all D codes used to Gerber reports window.

2007-12-23  Julian Lamb
        * gerber.c, many files: Start reorganization of some gerb_image
          parameters in preparation for adding final Gerber commands
          like rotation, mirroring, and knockout. Also, normalize all
          dimensions to inches in the image in order to simplify
          rendering.
        * tests/inputs/test-...: Add first three testsuite files to test
          new commands.

2007-12-20  Stuart Brorson (sdb@cloud9.net)
        * callbacks.c:  Add scrollbars to Gerber aperture report window
        since the report can grow to be very long.
        
2007-12-20  Julian Lamb
        * render.c,callbacks.c,interface.c: Connect rulers and scrollbars and start
          getting them functional.
        
2007-12-19  Stuart Brorson (sdb@cloud9.net)
        * src/gerber.c, src/gerb_stats.[hc], src/gerb_image.h,
        src/gerb_error.h, src/callbacks.c:  Implemented reporting
        of apertures found in Gerber files.  Added to Gerber 
        reports window.
        
2007-12-17  Julian Lamb
        * render,callbacks,interface: Restructure the whole rendering process by
          separating out all zoom and pan information from the global variable
          "screen". This was necessary to allow rendering without having a gtk
          window open, allowing for export from command line and many others.
          Also, the translation and zoom code is much more readable due to the
          elimination of many variables. Also, the GDK color allocations were
          eliminated to allow rendering without existing GDK colormaps in place.
        * gerbv.c: Create the basic framework for exporting from the command line.      

2007-12-16  Stuart Brorson (sdb@cloud9.net)
        * src/callbacks.c, src/render.c, src/gerber.c,
        src/gerb_error.h, src/gerb_stats.[hc]:  Implemented reporting
        of parse errors (with error level) found dring parsing of the 
        Gerber files.
        
2007-12-16  Stuart Brorson (sdb@cloud9.net)
        * src/callbacks.c, src/render.c, src/gerb_error.h,
        src/drill.c, src/drill_stats.[hc]:  Implemented reporting
        of all parse errors (with error level) found during 
        parsing of the drill file.
        
2007-12-16  Stuart Brorson (sdb@cloud9.net)
        * src/drill.[hc], src/drill_stats.[hc]:
        Fixed bug noticed by Joerg involving display of statistics 
        in drill file with M71 calling out metric units.
        
2007-12-14  Stuart Brorson (sdb@cloud9.net)
        * src/callbacks.c, src/render.c:  Added "General" tab to reports 
        windows for both Gerbers and Drills.
        * src/Makefile.am, src/drill.c, src/gerb_image.h,
        src/gerb_stats.[hc], src/drill_stats.[hc]:  Refactor drill_stats
        stuff to its own files in accordance with our function naming 
        scheme.

2007-12-14  Stuart Brorson (sdb@cloud9.net)
        * Too many files to mention:  Start adding list of drills found 
        to drill statistics reported.  Now "analyze->active drill layers"
        reports each drill defined, and the number of times it is used.
        
2007-12-14  Julian Lamb
        * render,callbacks: Fully separate GDK and cairo rendering code to help
          speed analization. Change from storing intermediate cairo patterns to
          xlib surfaces for speed improvement. Eliminate image compositing on
          each expose_event in order to make panning feel much quicker.
          Temporarily disable idle function to fix GDK memory leaks and crashes.
          
2007-12-12  Julian Lamb
        * src/gerbv.c: Fix half of bug #1443885 by eliminating segfault when
          project file has layer files that won't load.
        * src/callbacks.[ch],src/interface.c,src/render.[ch]: Big
          cleanup of callbacks.c and start moving zoom code to render.c in
          preparation for separating out zoom info from screen struct (allowing
          for exporting to file and improving code readability). Add in scrollbars
          and start hooking up rulers and scrollbar to panning.

2007-12-11  Julian Lamb
        * src/callbacks.c,src/interface,src/render.c: Get drag and drop working
          for layer sidebar. Fix memory leak for cairo rendering.

2007-12-10  Julian Lamb
        * src/gerbv.c,src/callbacks.c,others: Get basic layer management gui up
          and running. This includes visibility toggling, color picking, and basic
          row management using the buttons at the bottom. A popup menu will also
          be added when the user right clicks.
        * src/gerber.c: Fix polygon rendering bug (bug #1190809). This was due
          to the gerber parser not storing the correct polarity when closing
          a polygon.

2007-12-09  Stuart Brorson (sdb@cloud9.net)
        * src/callbacks.c, src/drill.c, src/render.[hc],
        src/gerb_image.[hc], src/gerb_stats.[hc]:  Added 
        beginnings of statistics report for drill files.

2007-12-09  Julian Lamb
        * src/gerbv.c,src/callbacks.c: Reattach project open/save stuff in gui
          and separate out some of the code back to gerbv.c.
        * gerbv.c,callbacks.c,interface.c,others: Implement export-to-file for
          PNG, PDF, SVG, and PS. Start implementing print functionality. More
          cleanup of old gui code. Move log handler over to new message textview
          in the sidebar.
          
2007-12-08  Julian Lamb
        * src/render.c,src/callbacks.c: Fix translation code for cairo renderer
          so things are correctly centered on the screen after a zoom-to-fit. Fix
          scaling code for MM unit drawings.
        * src/amacro.c,src/gerber.c: Fix error messages in amacro parsing (bug
          #1845782) on FreeBSD systems (thanks to Joerg for the patch). Also, fix
          possible hangs during amacro parsing (e.g. the file "%AM" would hang
          gerbv, since it didn't correctly check for EOF).

2007-12-07  SDB
        * render.c, render.h, Many other files:  Started to refactor
        gerbv.  Also start to incorporate statistics gathering stuff
        into gerber.[hc].

2007-12-07  Julian Lamb
        * src/drill.c: Fix warning messages on some drill files (bug #1316247).
          The drill parser did not zero out new gerbv_aperture_t structures, which
          sometimes allowed junk in the param[x] portions, which confused the
          parser and gave warnings and potentially incorrectly rendered drill
          holes.

2007-12-07  Julian Lamb
        * src/draw.c: Fix thermal rendering bug (bug #1024000) in the cairo
          rendering code (this bug is not easily fixable in the GDK code, but
          it is being obsoleted soon).

2007-12-06  Julian Lamb
        * src/callbacks.c,src/gerbv.c: Add private implementation of
          gdk_cairo_create to allow compilation with gtk < 2.8. Fixed bug in gerbv
          which was causing gdk rendering to skip frames sometimes.

2007-12-05  Julian Lamb
        * src/gerber.c,src/drill.h,src/gerb_image.h: Fix memory corruption issue
          with G54 codes not checking if aperture numbers were within bounds (bug
          #1843983). Also, bumped up max aperture number from 999 to 9999 based on
          reports of some CAD packages using numbers this hig (even though it
          clearly says 999 is the highest number in the RS274X spec). This will
          increase memory usage somewhat, but hopefully should be acceptable.

2007-12-05  Julian Lamb
        * src/drill.c: Fix parsing of drill files with commas in
          place of decimals (bug #1844100).

2007-12-05  Julian Lamb
        * src/draw.c,src/draw-gtk.c: Fix rendering of lines drawn with rectangular 
          aperatures (bug #1834944 and #1704942). Thanks to ineiev for the gdk
          patch, which was reworked to apply to the cairo rendering too.
          
2007-12-04  Julian Lamb
        * src/callbacks.[ch],src/interface.[ch]: Rename GTK widgets to more
          recognizable names for better code legibility. Change sidebar to a
          notebook view and add a messages tab. Organize statusbar layout. Add
          "analyze" menu and move CAM related functions to it. Clean up toolbars
          and combine into a single toolbar.
          
2007-11-30  Julian Lamb
        * src/callbacks.[ch],src/interface.[ch],src/gerbv.c: Split out all gui
          code out of gerbv.c and put it into the standard callbacks/interface
          files. Started to overhaul gui during the process. Also, speed up the
          feel of the cairo rendering by rendering layers to a cairo_pattern_t,
          then compositing using these patterns. This allows the user to pan and
          get much quicker response while the CPU renders the new view in the
          background.

2007-11-30  Stuart Brorson sdb (at) cloud9 (dot) net
        *  configure.in, src/exportimage.c, src/gerbv.c,
        src/pick-and-place.c:
        Modify build system so you must explicitly --enable-cairo to
        build using cairo, otherwise build using GDK by default.
        
2007-11-29  Stuart Brorson sdb (at) cloud9 (dot) net
        * src/gerb_file.c, src/gerber.c, src/gerbv.c, src/gerbv_screen.h,
        src/project.c:  Added "File -> Open Gerber(s)" dialog.  Added 
        int screen.last_loaded which keeps track of where to insert the next
        Gerber to be loaded.
        
2007-11-26  Julian Lamb

        * src/draw-gdk.[ch],src/gerber.c: Add gdk rendering code back in so it can
          be compiled if cairo isn't available.
        * src/gerber.c: Fix g_strconcat calls by adding NULL to end of arguments.
          
2007-11-20  Julian Lamb

        * src/draw.c: Add rendering code for arcs. Also, fix the rendiring of oval
          aperatures.

2007-11-19  Julian Lamb

        * src/draw.[ch], examples/am-test/am-test.gbx: Complete the conversion to
          the cairo rendering code. All aperature macros now render correctly, as
          well as clear layer polarities. Note that several bugs were found in
          the old aperature macro rendering functions (some rotations were not
          done correctly, and the moire and thermal outer diameters weren't
          correctly rendered) and those were fixed in the cairo conversion. The
          am-test.gbx file was modified slightly to test these fixes.
        * src/pick-and-place.c: Added an additional sanity check to make sure we
          don't accidentally open some gerber files as PNP place files.
        * configure.in: Add explicit cairo check.

2007-02-28  Julian Lamb

        * src/draw.[ch], src/draw_amacro.[ch], src/gerbv.c: Start converting
          rendering from gdk to cairo, in order to improve rendering capability,
          and allow for future export to PDF/SVG/PNG/PS capability. The
          draw_amacro files were combined into the draw files, since most of the
          rendering functions were common between the two.

2007-02-21  Julian Lamb

        * src/gerb_image.c, src/gerb_image.h: Added string label capability
          to the gerb_image struct for future rendering of labels.
        * src/pick-and-place.c: Updated parser to accept pick-and-place
          files output from the PCB program.  Performed more code cleanup
          and implemented min/max screen calcs based on pick-and-place
          files.
        * example/LED.xy: Added a sample pick-and-place file output
          from PCB, based on the LED example in the PCB source code.

2007-02-17  Julian Lamb

        * src/pick-and-place.c, src/pick-and-place.h, src/gerbv.c,
          src/csv.c:
          Get example/protel-pnp/Pick*.csv to load through the normal
          file loading code, implementing some simple logic to try
          and guess if a given file is pick and place data.

2007-02-16  Julian Lamb

        * src/pick-and-place.c, src/pick-and-place.h, src/gerbv.c:
          Continue cleaning up pick-and-place code into simple
          parser/renderer.

2007-02-15  Julian Lamb

        * src/search.c, src/search.h, src/search-gui.c,
          src/search-gui.h, src/search-cb.c, src/search-cb.h,
          src/search-file.c, src/search-file.h, src/search-mark.c,
          src/search-mark.h, src/pick-and-place.c,
          src/pick-and-place.h, src/Makefile.am: Remove all
          search* files, and combine important functions into
          pick-and-place.[ch].
        * src/gerbv.c, src/project.c: Remove gui-related references
          to pick and place functions in preparation for moving
          pick-and-place functionality to a simple parser/renderer.

2006-07-26  Stefan Petersen  <spe@localhost.localdomain>

        * src/log.c: Rewritten by Dino to use GTK2. The 
          previous caused SEGVs, so it was time to get
          it exchanged.

2006-07-25  Stefan Petersen  <spe@localhost.localdomain>

        * loads of files: Added check of return value for
          error checking.
        
        * configure.in, man/gerbv.1.in, src/Makefile.am:
          Remade build system so it should be able to handle
          autoconf 2.60 and automake 1.9. Thanks FSF for yet
          again breaking a working API.
 
2006-07-24  Stefan Petersen  <spe@localhost.localdomain>

        * src/gerb_file.c: Fixed bug #1236047, so now gerbv handles
          negative coordinates.

        * src/gerb_file.c, src/gerbv.c: Hopefully reduce SEGVs
          even more by better error checking of operations in
          gerb_fclose.

2006-07-23  Stefan Petersen  <spe@localhost.localdomain>

        * src/gerb_image.h, src/gerber.c, gerbv.c: Added patch from
          extensive (Sourceforge alias) that according to him make
          gerbv handles autoscaling of gerber files with mm better.

        * src/drill.c, src/gerb_file.c: Fixed some possible memory 
          leaks and SIGSEGVs pointed out by Wolfgang Wieser 
          (hand patched from #1201900).

2006-05-07  Stefan Petersen  <spe@localhost.localdomain>

        * src/draw_amacro.c: Daniel Mack - zonque submitted
          as a patch (1350283) (with no file attached though) that
          renaming stack_t to macro_stack_t would make gerbv build
          on darwin.

2005-09-28 Dan McMahill

        * src/drill.c: Remove an lval typecast.  Not only does this get
          gerbv to compile with gcc4 and other non-gcc compilers, it 
          was no longer needed as the types involved were all doubles 
          anyway.

2005-02-15  Stefan Petersen  <spe@siouxsie.umunet.org>

        * src/draw_amacro.c: Forgot to copy gc to local_gc
          so drawing inherits gc from image wide setting.
          Pointed out by Warren Young.

2005-02-08  Tomasz Motylewski  <t.motylewski@bfad.de>
        * src/gerbv.c: malloc strlen+2, not +1
        * src/gerb_file.c: malloc len+1, not len

2005-01-06  Stefan Petersen  <spe@siouxsie.umunet.org>

        * src/Makefile.am: A clean make distcheck by adding some missing
          .h-files in Makefile.am

        * src/*.c: Removed portability to GTK+ 1.x by changing configure.in
          and remove USE_GTK2 in many small places. Also made some reformat
          of the code to fit into the rest of the gerbv codebase.

2004-12-28  Stefan Petersen  <spe@siouxsie.umunet.org>

        * src/draw.c: When drawing circles I ignored if circle
          had inner diameter, which was pointed out by Harry Eaton. 
          Not anymore... Closes bug #1050340 in this branch.

        * Updated to TinyScheme 1.35

2004-10-30  Stefan Petersen  <spe@siouxsie.umunet.org>

        * src/draw_amacro.c: Forgot to use local_gc when drawing some
          of the primitive aperture macros. Closes bug #1051045.

2004-10-13 Juergen Haas <juergenhaas@gmx.net>

        * right click on selected part (current active selection) now works 
          also on shapes with PIN1 Off centre axis
          FIXME circular shapes are recognised  at a fixed radius of 3mm 
          Only works with units of gerbv match units used in pick and place 
          file!

        -saving projects:
        is done in a more flexible way:
        adds a similar line with "filename" replaced by "pick_and_place" 
        to project file
FIX ME: reading in a project file is still broken 
        -several bugfixes:

          16-19 by loading a "Pick and Place" file in CSV Format: 
                         entry1,entry2,..
                NO OTHER FORMAT IS RECOGNISED SO FAR!

                   how to read in and parse pnp file
                - src/search_mark.c:
                   create_marked_layer(layernumber); will draw the selected 
                   parts as circles with a line going from centre to Pin1 on
                   the layer given as argument(at the moment layers 16-19 are

                   the desired items (for multiple selections by mouse click use
                   the well-known SHIFT-CTRL-click combinations)

        * This version also includes first rough support for MINGW/WIN32 
          -not yet usable, route for reading in files is broken

2004-08-21  Stefan Petersen  <spe@stacken.kth.se>

        * src/gerbv.c: Made sure that only list of short options is 
          printed when only short options are compiled in.

2004-08-16  Stefan Petersen  <spe@stacken.kth.se>

        * doc/*, example/*: Makefiles.am removed Makefile.in wheh running
          distclean. Not good. Spotted by Hamish Moffatt when packaging
          for Debian.

2004-07-28  Stefan Petersen  <spe@stacken.kth.se>

        * src/draw.c: In gerbers the image can be negative or positive.
          Then a part of the image called a layer can be clear or dark.
          -"No more weed for you, Mr Gerber".
          Richard Lightman found this and submitted both an example and 
          a patch. Thanks!

2004-07-11  Stefan Petersen  <spe@stacken.kth.se>

        * src/draw_amacro.c: When drawing thermals the cross ends in butt
          instead of round which gives nicer look when thermal covers an 
          other via.

2004-06-27  Stefan Petersen  <spe@stacken.kth.se>

        * src/gerber.c: Improved comments on what is going and why. Also
          improved a little in determining the size of the image. Now it 
          ignores points with no aperture defined, unless it is a polygon 
          area.

2004-06-24  Stefan Petersen  <spe@stacken.kth.se>

        * src/gerber.c: Removed two potential segfaults when running old
          RS-274D format.

        * src/gerber.c, src/batch.c, src/gerb_image.[hc]: Actually removed
          all traces of MQ_END and MQ_START. That means that empty nodes 
          with only this information isn't saved, since the only time we need
          this information is when parsing arcs. When an arc is parsed
          the information wheter that arc is multi or single quadrant is
          saved there. Also closes bug #942590.

        * src/gerbv.c, src/gerbv_screen.h, src/gerb_image.c, src/gerb_image.h:
          Added possibility to dump a parsed image as text to be able to
          debug the parser.

2004-06-10  Stefan Petersen  <spe@stacken.kth.se>

        * src/draw_amacro.c: By mistake I assumed that all aperture 
          macros had exposure flags, but that was a mistake. Drew Moore
          pointed it out to me. Thanks.

2004-06-05  Stefan Petersen  <spe@stacken.kth.se>

        * */.cvsignore, man/gerbv.1.in, src/gerbv.c: Minor updates and 
          cleanups from Dimitri. --help added for instance.

-- Release 0.16 --

2004-05-25  Stefan Petersen  <spe@stacken.kth.se>

        * src/draw_amacro.c: Now aperture macros handles exposures properly,
          so some thermals can be drawn properly. Inspired by discussion with
          Dimitri.


2004-05-19  Stefan Petersen  <spe@stacken.kth.se>

        * man/gerbv.1.in, src/Makefile.am, src/drill.c, src/gerbv.c, 
          src/tooltable.c, src/tooltable.h: Patch from Dimitri 
          (lastname unknown) to read tool files from for instance Eagle CAD.

2004-04-27  Stefan Petersen  <spe@stacken.kth.se>

        * configure.in, src/drill.c: Patch from Tomasz Motylewski as a start
          remove dependencies on mmap et al (sys/mman.h) for targets lacking
          these operations (mingw).

2004-04-21  Stefan Petersen  <spe@stacken.kth.se>

        * src/gerbv.c: Added keys f for fit, z for zoom in and Z for zoom out
          after request from Stefan Thiede.

2004-04-04  Stefan Petersen  <spe@stacken.kth.se>

        * src/gerb_file.[hc], src/drill.c, src/amacro.c, gerber.c:
          Changed gerb_fgetint() so it can return number of parsed characters.
          This is useful when parsing coordinates in omit trailing zeros mode.
          Omit trailing zeros is also handled properly now. Reported by Joachim
          Jansen and filed as bug #918344.
        
2004-02-24  Stefan Petersen  <spe@stacken.kth.se>

        * src/gerbv.c: Apperently under GTK2 both delete_event and destroy
          signals is emitted when you press the little cross in the 
          decoration bar. When both signals were emitted gerbv tried to free
          the same memory twice.

2004-02-14  Stefan Petersen  <spe@stacken.kth.se>

        * src/Makefile.am: Making sure init.scm is copied to the right 
          place at install.

2004-02-13  Stefan Petersen  <spe@stacken.kth.se>

        * src/gerber.c: The good old circles revisited. This time Dan
          noticed that circles with the same start and end point did not 
          draw properly ie as circles. It became points.

2004-02-08  Stefan Petersen  <spe@stacken.kth.se>

        * configure.in: Apperently auto* doesn't define $prefix if you
          don't set it in your script. The autotools has become more and
          more of a moving target...

        * man/gerbv.1.in: A bunch of updates, mainly reflecting the new
          features.

2004-02-07  Stefan Petersen  <spe@stacken.kth.se>

        * src/gerbv.c: Save screen.path even when we load a project file.

        * src/gerbv.c: Fixed a segmentation fault when I tried to free
          an optarg:ed variable.

2004-02-05  Stefan Petersen  <spe@stacken.kth.se>

        * src/gerbv.c: Dan strikes again. Option -p (with appropriate 
          error message) added as an alternative to --project.

2004-02-01  Stefan Petersen  <spe@stacken.kth.se>

        * src/gerbv.c: Patch from Dan causes the "save as..." dialog box 
          to come up if you try to do a "save" with no current project 
          file name.
        * src/gerbv.c: Yet another patch from Dan to put project filename
          in title of window.

2003-12-14  Stefan Petersen  <spe@stacken.kth.se>

        * configure.in, src/gerbv.c, src/log.c, src/setup.h: It is now 
          possible to compile gerbv with GTK+ 2.*, at least tested with
          2.2.4. There are still some problems, particulary in log.c. 
          GtkText is deprecated, but I have enabled GTK_ENABLE_BROKEN.
          This needs a more permanent solution. This closes Feature 
          Request #771480, but probably opens up some new ones.

2003-12-10  Stefan Petersen  <spe@stacken.kth.se>

        * src/gerbv.c: Projects saves and restores background color.

        * src/gerbv.c, src/gerbv_screen.h: Added Save Project and handles
          if a filename was given, either when loading or a previous save.

2003-12-09  Stefan Petersen  <spe@stacken.kth.se>

        * configure.in, */Makefile.am: Added a recursive chain of Makefile.am
          to be able to run make dist and make distcheck. Proposed by Dan 
          McMahill. Thanks!

2003-12-07  Stefan Petersen  <spe@stacken.kth.se>

        * src/gerbv.c, src/project.[hc]: Project now saves ev. inversion of
          layer, all layers accept all parameters and commandline switch
          --project=<project file> also works.

        * src/gerbv.c, src/gerbv_screen.h: Added invert layer functionality.
          Closes feature request 777547.

2003-12-06  Stefan Petersen  <spe@stacken.kth.se>

        * src/gerb_file.[hc]: Added function gerb_find_file.
        * src/draw_amacro.c: Forgot to make some internal functions static.
        * src/*: Scheme interpreter added to be used by project files as a 
          start. Also project file handling added. A short description of
          the format used in project files also added. A massive commit.

2003-11-22  Stefan Petersen  <spe@stacken.kth.se>

        * configure.in, acconfig.h: acconfig.h removed and more information
          added to configure.in after information in warning messages from
          autoheader.

2003-11-13  Stefan Petersen  <spe@stacken.kth.se>

        * src/export_image.c: Changes pixbuf_to_file_as_png simplify operation
          No major speedup since that is not the time hog.

-- Release 0.15 --

2003-10-06  Stefan Petersen  <spe@stacken.kth.se>

        * src/draw_amacro.c: Drawing of aperture macro primitive 7 was
          severly broken. Revealed by Drew Moore who sent an example 
          along. Thanks Drew! Closes bug #818307.

2003-09-28  Stefan Petersen  <spe@stacken.kth.se>

        * src/gerber.c: Patch from Peter Brueckner. Some Gerbers don't
          have G04 but just G4. Peters patch fixes that for G- and M-codes.

2003-09-08  Stefan Petersen  <spe@stacken.kth.se>

        * src/gerber.c: Patch from Simon Munton to fix a problem with polygons
          sometimes not being filled properly. Closes bug #800928 (which
          he promptly had submitted).

        * src/gerber.c: Another patch from Simon. This time it fixes
          circular polygon outlines by with a number of short segments.
          Closes bug #603183, which was almost a year old. Thanks Simon!

-- Release 0.14 --

2003-05-31  Stefan Petersen  <spe@stacken.kth.se>

        * configure.in, src/amacro.c: Removed the last remaining malloc.h
          after tips from Charles Lepple on the geda mailinglist.

2003-04-18  Stefan Petersen  <spe@stacken.kth.se>

        * src/draw_amacro.c: Larry Doolittle had a problem when drawing
          one of his files, a circle seemed to explode. I couldn't 
          reproduce it, but after his tests I added this patch. Thanks Larry!

2003-04-07  Stefan Petersen  <spe@stacken.kth.se>

        * src/gerber.c: RS274D caused segfaults again. Reported by Skurk.

-- Release 0.13 --

2003-03-16  Stefan Petersen  <spe@stacken.kth.se>

        * src/draw.c, src/gerb_image.h, src/gerber.c: Angles are now
          calculated as doubles instead of ints. For instance, the cslk
          example now draws properly at the same time as Dans ridicously
          small arcs also works.

        * src/gerber.c: Better sanity checks for angles of arcs, so
          cw are drawn cw and ccw are drawn ccw. Closes bug #703265
          which was reported by Mark Whitis. Thanks!

2003-03-10  Stefan Petersen  <spe@stacken.kth.se>

        * src/gerber.c: Doesn't warn anymore if a gerber file requests an
          image rotate on zero degrees. Reported by Balaji V.

2003-03-02  Stefan Petersen  <spe@stacken.kth.se>

        * src/draw_amacro.c: Aperture macro primitive 1 is a filled circle.
        * Makefile.am, configure.in, src/gerbv.c, src/Makefile.am, 
          src/gerbv.1.in: Removed all traces of Guile. batch.c is left, but 
          is not compiled in.

2003-03-01  Stefan Petersen  <spe@stacken.kth.se>

        * src/gerb_image.[hc], gerber.c: Redesigned step-and-repeat
          parser. And when I was at it I also cleaned up new_gerb_image()
          a bit.

2003-02-24  Stefan Petersen  <spe@stacken.kth.se>

        * src/Makefile.am,src/gerbv.c,src/gerbv_screen.h,src/log.c,
          src/setup.[hc]: Added setup to handle all things that can
          be setup by commandline or (future) rc files. We have the
          screen variable, but some didn't think it was appropriate
          to add setup things to.

2003-02-22  Stefan Petersen  <spe@stacken.kth.se>

        * src/gerber.c: Changed comparision if two angles are equal
          to double since Dan McMahill discovered a case where the difference
          between the angles were actually less than 0.5 degrees.  
          Closes bug #689663.

        * src/gerbv.c: I you tried to swap layer with an unused layer 
          gerbv segfaulted. Also discovered by Dan McMahill. Cudos to him
          as usual... Closes bug #689667.
        
2003-02-12  Stefan Petersen  <spe@stacken.kth.se>

        * src/gerber.c: A patch from Peter Monta for incremental
          coordinates. He also discovered that I had made a mistake
          when parsing incremental/absolute coordinates.

-- Release 0.12 --

2003-02-06  Stefan Petersen  <spe@stacken.kth.se>

        * src/drill.c; Exchanged the last fprintf(stderr, with
          GERB_COMPILE_ERROR.

        * src/gerbv.c: Added swap of tooltips information too.

2003-02-02  Stefan Petersen  <spe@stacken.kth.se>

        * src/drill.c: Added patch from Dan McMahill since + sign
          before coordinates seemed to confuse the drill parser.
          Closes bug #678407.

        * src/gerbv.c: Now you can move around layers in the right
          sidebar so you can select in which order the layers should 
          be presented.

        * src/draw.c, src/drill.c, src/gerb_image.[hc], src/gerber.c:
          A new system to keep track of mm and inches. Everything is
          still drawn based on inches and min/max is also stored as
          inches. But now every aperture and every coordinate has a 
          unit attached to it that is used when drawing. I hope I 
          haven't breaked anything, patricular in drill.c. And I have
          very few (one) reference examples in millimeters.

2003-01-26  Stefan Petersen  <spe@stacken.kth.se>

        * src/log.[hc], src/gerbv.c: Made sure error messages are 
          directed to the right place (shell and popup) at the
          right moment and that the error messages look nicer.

        * .cvsignore, man/.cvsignore, scheme/.cvsignore, src/.cvsignore:
          Added these files submitted by Holger Waechtler. Thanks!

2003-01-25  Stefan Petersen  <spe@stacken.kth.se>

        * src/gerber.c, src/gerb_image.[hc]: Added a patch from
          Holger Waechtler regarding G70/G71 which opened up a whole
          can of worms. After thinking and hacking the following works:
          * all in inches (as always).
          * apertures in inches and vectors in millimeters.
          The reason for not fixing apertures in millimeter are because
          the calculation must happen in the drawing engine, since we
          don't know until the moment of drawing if the paramters defines
          a length or an angle. It's probably just a matter of fixing the
          scaling when drawing, but I fix that later on.

2003-01-19  Stefan Petersen  <spe@stacken.kth.se>

        * src/gerber.c: Fixed bug in arc/circle drawing that caused
          some odd cases (not noticed so far elsewhere) that made
          ccw arcs to be drawn cw. Discovered by Jukka Marin. Thanks.

2003-01-16  Stefan Petersen  <spe@stacken.kth.se>

        * man/gerbv.1, src/gerbv.c : Updated documentation to reflect
          the new log commandline switch.
        * files2tag, TODO: Minor documentation updates to reflect
           reality.

2003-01-15 Stefan Petersen  <spe@stacken.kth.se>

        * src/Makefile.am, src/color.c, src/draw.c, src/drill.c,
          src/gerber.c, src/gerbv.c, src/gerbv_screen.h. Added are
          src/log.[hc], src/gerb_error.h: Finally have managed to
          change all error reporting routines so it works with
          Dinos log system. Now should all errors and warnings pop up
          in an explicit window so it behaves like a proper 
          X-application. Thanks to Dino I got this fixed. Maybe
          all code is not what Dino expected, but anyhow I owe him
          a great THANKS. Maybe all compilation errors should have
          "return;" after them?

2003-01-14  Stefan Petersen  <spe@stacken.kth.se>

        * src/gerbv.c: A fix for the previous fix. The previous fix
          was not good and had to be redone. now. We check the
          parsed image before we put it in use so we don't have to
          save alot of thing to be able to back off if error.

2003-01-13  Stefan Petersen  <spe@stacken.kth.se>

        * src/gerbv.c: When gerbv discovered RS274D and terminated
          it tried to free memory to hadn't been allocated due to 
          it had discovered error in the gerber file. This caused
          windows to never close and segfaults when terminating.

2002-12-25  Stefan Petersen  <spe@stacken.kth.se>

        * src/gerbv_screen.h, src/gerbv.c: Changed how the
          different windows are stored in the screen struct.
        * src/amacro.h: Forgot to include stdlib.h which was needed
          to remove warnings regarding free missing.
        * src/gerbv.c: Minor beautification cleanups.

2002-12-11  Stefan Petersen  <spe@stacken.kth.se>

        * src/gerbv.c: Fixed 64-bit compilation warning by casting
          gpointer to long int. Closes bug #642703.

2002-12-09  Stefan Petersen  <spe@stacken.kth.se>

        * src/gerber.c: Fixed some kind of bug causing some filled 
          polygons not to get displayed. Reported by Chris Ellec. 
          Closes bug #649663.

2002-12-02  Anders Eriksson  <anders@umunet.org>

        * configure.in, src/amacro.c: Applied patch from 
          Charles Lepple to fix bug #646268 (building on MacOS X).

2002-11-26  Anders Eriksson  <anders@umunet.org>

        * src/gerbv.c: Fixes bug #643799 (zoom out_line stopped
          working).

2002-11-26  Stefan Petersen  <spe@stacken.kth.se>

        * src/gerbv.c: Added idea and (hacked up by me) patch for
          turning all layers on and off from Martin Sigrand. It should
          really need an overhaul regarding non freed memory.

2002-11-24  Stefan Petersen  <spe@stacken.kth.se>

        * doc/eagle/*: Added information for Eagle CAD users from
          Daniel Dorau. It also made the webpage. Thanks Daniel!  

        * src/gerber.c: Yet another G-code (55) discovered in an
          example in the "standard" by our russian friend Yuri.

2002-11-23  Stefan Petersen  <spe@stacken.kth.se>

        * src/amacro.c, src/draw.c, src/draw_amacro.c, src/gerber.c:
          More files with the same mistake in as below. I cleaned up 
          my own mess this time.

2002-11-23  Anders Eriksson  <anders@umunet.org>

        * src/gerbv.c: Fixed bug 642600, Don't use default labels without
          any statement after. Also use comments for label after #endif.

-- Release 0.11 --

2002-11-19  Stefan Petersen  <spe@stacken.kth.se>

        * src/gerbv.c: Anders optimized drawing optimized away setting
          of superimpose function. Not any longer. Daniel Dorau pointed
          out this and the one below.

        * src/draw.c: Hopefully fixed the one pixel gap between lines
          when it should be a filled area.

2002-11-17  Stefan Petersen  <spe@stacken.kth.se>

        * src/exportimage.c: Background color was ignored. Noticed by Dino.

2002-11-16  Stefan Petersen  <spe@stacken.kth.se>

        * src/gerbv.c: Made sure all cancels and destroy_event from 
          different popup windows are handled and destroyed properly.
          Also made some minor fixes in new "set explicit scale" functions.
        * src/gerbv.c: Made explicit set scale also center image properly.

2002-11-15  Stefan Petersen  <spe@stacken.kth.se>

        * src/gerbv.c: Robustified if someone tries to parse RS274D.
          Happend to fix bug #639127.
        * doc/PNG-print/*: Added doc on how to print PNGs generated by gerbv.
        * src/gerbv.c: Added explicit setting of scale. Good when generating
          PNGs for printing. Both patch and above doc is thanks to 
          Dino Ghilardi.

2002-11-15  Andreas Andersson  <e92_aan@e.kth.se>

        * src/drill.c: Slight change to allow broken drill files from
          Orcad386. Not pretty. But then again, neither is Orcad.

2002-11-07  Anders Eriksson  <anders@umunet.org>

        * src/gerbv.c: Minor cleanups, prepare idle_redraw to
          be reentrant to allow calling it more than once (i.e.
          for png export as well as for screen redraw).

2002-11-06  Anders Eriksson  <anders@umunet.org>

        * src/gerbv.c: Re-read some gtk-docs, we weree mistreating
          the gtk_idle-functions. This patch fixes this and closes
          pixmap leakage caused by complete redraw when we had a
          preempted state.
          Oops, you need to start the idle function at least once.

2002-11-05  Anders Eriksson  <anders@umunet.org>

        * src/gerbv.c, src/gerbv_screen.h: Removed clipping/no
          clipping kludge since export_png now behaves as Dino
          expects. We should make a function of common code in
          export_png and redraw_pixmap to make it more maintainable.
        * src/gerbv.c (redraw_pixmap): Don't try to sneak out doing
          events from redraw_pixmap, check for them and preempt if
          there are events on queue. This closes the everythinh-is-
          not-redrawn-sometimes bug (I hope).

2002-11-04  Stefan Petersen  <spe@stacken.kth.se>

        * src/exportimage.c, gerbv.c: export_png now export whole image
          despite whats displayed (still depending on zoom/scale thou).
          If export_png receives an imagetosave, that will be the image
          that will be saved, so it's more general now. Must hack some
          more to be able to utilize both ways. Anders can happily remove
          all what he calls kludges.

2002-10-31  Stefan Petersen  <spe@stacken.kth.se>

        * src/gerber.c: Yet another commando that doesn't complain if 
          default values are given. AS is the lucky one this time.
        * src/gerber.c, src/draw.c: By considering an undefined aperture
          despite we didn't draw caused strange lines around the first line
          drawn.

2002-10-31  Anders Eriksson  <anders@umunet.org>

        * src/gerbv.c: Replace incremental redraw with clipping
          option. It is now possible to turn clipping off, this
          might be useful for export png (sorry for breaking this,
          Dino).

2002-10-30  Stefan Petersen  <spe@stacken.kth.se>

        * src/gerb_image.h, src/gerber.c: Implemented %SF% and %SR% in
          parser, but ignored the draw engine. If any of these parameters
          not are default a warning is issued. Closed a feature request.

2002-10-30  Anders Eriksson  <anders@umunet.org>

        * src/gerbv.c, src/gerbv_screen.h: Added restartable
          redraw by keeping redraw state between calls to
          redraw_pixmap(). Also added drawing status on statusbar.

2002-10-29  Stefan Petersen  <spe@stacken.kth.se>

        * src/draw_amacro.c: Fixed a bug when drawing primitive 20
          discovered by jj. Caused slanted (by coordinates) primitives
          to "slant" in the wrong direction.

2002-10-29  Anders Eriksson  <anders@umunet.org>

        * src/gerbv.c (redraw_pixmap): Free pixmaps also when
          preempted, we used to leek pixmaps (bad!).

2002-10-28  Anders Eriksson  <anders@umunet.org>

        * src/gerbv.c (autoscale): Wrong sign on clip_bbox.x1 from
          trans_x. Now even nollezappare is centered correctly.

2002-10-27  Stefan Petersen  <spe@>

        * src/draw_amacro.c: Reset the stack pointer after each primitive
          operation. It's not completly right to do it this way, but since
          I built the compiler I know how the code generated looks like ;-).
          Closes bug #629101.

2002-10-26  Stefan Petersen  <spe@stacken.kth.se>

        * src/gerber.c: Removed some nested use of strncmp with simple
          switch/case instead in parse_G_code.
        * src/gerber.c: Added an extra check so RS274D doesn't casue
          segfault. Discovered by Jukka Marin. Thanks.

2002-10-24  Anders Eriksson  <anders@umunet.org>

        * src/gerbv.c, src/gerbv_screen.h: Played with clipping. Allocated
          pixmap is now same size as window. GTK does all clipping (we
          could optimize this somewhat with "object" bounding boxes). This
          makes it possible to zoom where no gerbv has zoomed before.
          Some interesting effects can be found by zooming in a lot.

-- Release 0.0.10 debian release 2 --

2002-10-18  Stefan Petersen  <spe@stacken.kth.se>

        * src/drill.c, src/gerb_file.[hc], src/gerber.c, src/gerbv.c:
          Alot of abuse using EOF(-1) when char actually is unsigned
          caused a lot of warnings when Debian build system tried to
          build it for a couple of platforms.

2002-10-14  Anders Eriksson  <anders@umunet.org>

        * src/gerbv.c: Activate millimeters in unit menu if this
          is the default unit.
          (update_statusbar()): Check that statusbar has been
          created before trying to set text to it. This eliminates
          an annoying GTK assertion.

-- Release 0.0.10 --

2002-10-13   Stefan Petersen  <spe@stacken.kth.se>

        * configure.in: Updated version to 0.0.10

2002-10-11  Anders Eriksson  <anders@umunet.org>

        * configure.in, acconfig.h, src/gerbv.c: Added configure-option
          to change default unit for status bar to millimeters instead
          of the built-in default of mils.

2002-10-09  Stefan Petersen  <spe@stacken.kth.se>

        * src/gerber.c: The undefined aperture fix below is, in princip,
          only valid if aperture type != from aperture macro.

2002-10-07  Stefan Petersen  <spe@stacken.kth.se>

        * src/gerber.c: If aperture was undefined (as in polygon outline)
          it caused a segfault in min-max routine. Closes bug #619652.

        * man/gerbv.1.in: Added blurb about the new command line 
          switches. Also added some text on backends.

        * src/gerbv.c: Added some GDK/GTK specific command line
          parameters. Also added the parameter --geometry.
          Currently ignoring placement parameters, though I parse them

2002-10-06  Anders Eriksson  <anders@umunet.org>

        * src/gerbv_screen.h, src/gerbv.c: Added menu selection for
          units. Decreased width of status bar. This closes the too
          wide window problem in bug #615475. The default minimum
          height is still too high to fit in an 800x600 display.
          By limiting the number of files to 17 or so this problem
          is also solved.

2002-09-29  Anders Eriksson  <anders@umunet.org>

        * src/gerber.c, src/gerbv.c, src/gerbv_screen.h: Removed last
          traces of IMG_EXTRA hack. Now using proper aperture width to
          increase width of bounding box. This may give slightly too
          big bbox, but it is better than before. I consider this to
          close bug #605985.

2002-09-17  Stefan Petersen  <spe@stacken.kth.se>

        * configure.in: exportpng is configured in default and removed
          if asked (--disable-exportpng).
        * configure.in, acconfig.h, src/gerbv_screen.h: Setting of MAX_FILES
          from ./configure.
        

2002-09-09  Stefan Petersen  <spe@stacken.kth.se>

        * src/gerbv.c: Added version number in main windows title.
        

2002-09-07  Stefan Petersen  <spe@stacken.kth.se>

        * src/batch.c, src/draw.c, src/gerb_image.h, src/gerber.c, 
          src/gerber.h: Changed how multiquadrant circles are supported.
          Now it's more of a state, before it was considered an interpolation.
          Therefore not all multiquadrant circles were detected as such and
          got defined wrong. Some parts of the EAGLECAD_KLUDGE was removed,
          though EagleCad had some other surprises in store.
        * src/amacro.[hc], draw.c, draw_amacro.[hc]: Dynamic allocation
          of stack when drawing aperture macros. Closes the evil bug 603147.
        

2002-09-02  Stefan Petersen  <spe@stacken.kth.se>

        * src/batch.c, src/draw.c, src/gerb_image.h, src/gerber.c:
          Polygon drawing got it's own gc (pgc) since we must have 
          our own outline pen size. Now we don't have to have an aperture
          defined to be able to draw polygon areas. Closes bug 602965.
        * Removed PAREA_FILL as an interpolation. Has only PAREA_START
          and PAREA_END left so the application has to keep track if it's
          in polygon area fill or not by itself. PAREA_FILL was not a
          proper "interpolation", it is instead any of the other 
          interpolations. Closes bug 603146.


2002-09-01  Stefan Petersen  <spe@stacken.kth.se>

        * src/draw.c: Polygon Area Fill could never have worked at
          all since number of points reported to gdk_draw_polygon
          always was zero.

2002-08-31  Anders Eriksson  <anders@umunet.org>

        * src/gerbv.c (redraw_pixmap): Removed redundant bounding
          box calculation.

2002-08-27  Anders Eriksson  <anders@umunet.org>

        * src/gerbv.c, src/gerbv_screen.h, src/gerbv_icon.h: Calculate
          proper initial translation when doing autoscale. Center image.
          Added #define for extra 0.1 inches in autoscale. New icon image.
          Also added outline debugging code (within #ifdef's).

2002-08-27  Andreas Andersson  <e92_aan@e.kth.se>

        * src/drill.c: Minor change to the drill file format guessing
          logic to allow for yet another special case.

2002-08-27  Stefan Petersen  <spe@stacken.kth.se>

        * src/gerbv.c: Fixed a couple of minor memoryleaks in color
          allocation with valgrind after a tips from Anthony J Bybell.

2002-08-10  Stefan Petersen  <spe@stacken.kth.se>

        * src/gerbv.c, src/Makefile.am, files2tag.txt modified, 
          src/scm_gerber.[hc] removed, src/batch.[hc] added: 
          All batch functionality broken out to one place, ie batch.[hc].

2002-08-09  Stefan Petersen  <spe@stacken.kth.se>

        * src/gerbv.c: Removed two lines causing zoom to stop work
          when a non-loaded layer recently had been selected or deselected.
          I didn't find a reason for these two lines to be there. Maybe
          there was... Closes bug 593109.
        * src/gerbv.c, src/gerbv_screen.h, man/gerbv.1.in: Added 
          activation/deactivation via the keyboard. Closes feature request
          593104. Also updated the man page with this info and fixed other
          minor stuff.

2002-08-04  Stefan Petersen  <spe@stacken.kth.se>

        * src/gerbv.c, src/gerbv_screen.h: Added superimposing selectable
          function to be used when you put "layer upon layer". I call it
          superimposing functions. Hope it's correct english.
        * man/gerbv.1.in: Minor layout changes and added part on superimposing
          functions.
        * src/gerbv.c: Fixed GTK asserts popping up when starting gerbv
          without any files loaded.

2002-08-01  Stefan Petersen  <spe@stacken.kth.se>

        * src/draw.[hc], src/gerbv.c: Changed how layers are created and
          stored to be able to be displayed on top of each other. This
          is based on a grand idea from Dino Ghilardi.

2002-07-24  Andreas Andersson (e92_aan@e.kth.se)

        * src/drill.c: Changed the parser to catch undefined tools
          and insert default values. It warns the user, though.
          Fixed a slight bug in min/max coordinate finding.

2002-07-16  Stefan Petersen  <spe@stacken.kth.se>

        * src/gerbv.c: Fixed bug 573016, some gerbers not drawn.
          always do fabs on floats not abs.
        * src/gerb_image.[hc], gerber.c: Parses and stores %IN%
          ie the image name.

2002-07-15  Anders Eriksson  <anders@umunet.org>

        * src/gerbv.c, src/gerbv_icon.h: Added application icon.

2002-07-13  Stefan Petersen  <spe@stacken.kth.se>

        * configure.in: Added --with-gtk-config to fit FreeBSD 
          after patch from Bruno Schwander <bruno@tinkerbox.org>.
        * example/ekf/README: Fixed bug 578583 basically saying that
          this example shouldn't work.
        
-- Release 0.0.9 --

2002-07-06  Stefan Petersen  <spe@stacken.kth.se>

        * configure.in: Updated version to 0.0.9.
        * man/gerbv.1.in: Updated man page with new features.

2002-07-05  Anders Eriksson  <anders@umunet.org>

        * src/gerbv.c: Save a widget by adding a leading space in
          statusbar.

2002-07-04  Anders Eriksson  <anders@umunet.org>

        * src/gerbv.c: Statusbar => Label to allow setting a fixed
          width font and thus avoid getting the coordinates to move
          as the number of digits change. Moved font names to header
          file. We should consider using a rc-file for font names and
          colours and stuff.
          Made status bar not expandable.

2002-07-02  Anders Eriksson  <anders@umunet.org>

        * src/gerbv.c, src/gerbv_screen.h: Macrofied coordinate unit
          conversions to have the constants in one place. Converted
          sprintf()s to safer snprintf()s.

2002-07-01  Anders Eriksson  <anders@umunet.org>

        * src/gerbv_screen.h: Bounding box needs to be doubles, not
          ints.
        * src/gerbv.c (motion_notify_event): Finally it seems I got 
          the absolute coordinates right. Partly closes feature
          request 567965 (still need to add error messages and fix
          the layout).
          * Fixed some of the layout issues. Now uses only one statusbar
          widget instead of three. The message is composed from three
          strings. Still no error messages.

2002-06-20  Anders Eriksson  <anders@umunet.org>

        * src/gerbv.c: Mils are 0.001 inch and not 0.01, thanks Dan!
          This closes bug #571097.

2002-06-19  Anders Eriksson  <anders@umunet.org>

        * src/gerbv.c (motion_notify_event): py, not px!
        * src/gerbv.c, src/gerbv_screen.h, src/draw.c: Added bounding
          box translations to get correct gerber coordinates (second
          try, did I make it?).

2002-06-18  Stefan Petersen  <spe@stacken.kth.se>

        * src/gerbv.c: Added background color selection. Closes feature
          request 557365.
        
2002-06-17  Anders Eriksson  <anders@umunet.org>

        * src/gerbv_screen.h: added msgid for stausbar.
        * src/gerbv.c: Changed coordinate output both in statusbar and
          in measure mode. Now using mils and mms as units. Coordinates
          are now correct in respect to the gerber coordinate system
          (at least that's what I think). Too much information is shown
          in the statusbar, we will have to add unit selection (either
          mils or mms). Minor layout change for statusbar (I need to
          learn gtk layout better!).

2002-06-17  Stefan Petersen  <spe@stacken.kth.se>

        * src/draw.c: Ignored if lines were using rectangular apertures
          to draw. Closes bug 567128.

2002-06-13  Anders Eriksson  <anders@umunet.org>

        * src/gerbv.c, src/gerbv_screeen.h: Added statusbar, prints cursor
          position as well as distance when measuring.

2002-06-12  Stefan Petersen  <spe@stacken.kth.se>

        * src/gerbv.c: Fixed autoscale() not to translate image out of
          window. Happened after fix for negative coordinates. Should
          translate image to center of window.
        * src/draw.c: Moved setting off err_gc outside loop so it's always 
          done, even if you don't need it.

2002-06-12  Anders Eriksson  <anders@umunet.org>

        * src/gerbv.c (draw_zoom_outline): Fix division by zero when
          drawing a zoom box with no delta y. Closes bug 567166.

2002-06-11  Stefan Petersen  <spe@stacken.kth.se>

        * src/gerb_file.c: Changed ENODATA to EIO, which is more portable.
          Closes bug 567179.
        * src/gerbv.c: It is now possible to draw images with negative
          coordinates. Closes bug 548094.
        * src/draw.[hc],src/draw-amacro.[hc], src/Makefile.am: Split out 
          aperture macro stuff from draw.c to a separate file, draw_amacro.c.
        * src/draw_amacro.c: Fixed bug when drawing primitive 4 causing
          rotation to be wrong. Thanks to Jonas (you know who you are) for 
          the excellent files.
        * src/draw_amacro.c: Changed interpretation of "closed shape" in
          primitive 4. If first point is the same as the last point it's
          a closed shape, ie filled according to my interpretation. Don't
          know if it's a correct interpretation.

2002-06-10  Anders Eriksson  <anders@umunet.org>

        * src/gerbv.c: Centered outline zoom uses shift instead of control,
          use shift before clicking with button three to initiate centered
          outline zoom (rm:ed switching between centered and plain outline).
          Changed distance output format to add more digits.

2002-06-09  Anders Eriksson  <anders@umunet.org>

        * src/gerbv.c: Fix actual zoomed area for centered outline zooming.

2002-06-09  Anders Eriksson  <anders@umunet.org>

        * src/gerbv.c: Set cross hair cursor as soon as shift key is
          pressed (in normal mode, i.e. not zoom outline). Added centered
          zoom outline mode (closes Feature Request 553452).

2002-06-09  Anders Eriksson  <anders@umunet.org>

        * src/gerbv.c: Added measure distance color. Added actual zoom
          box for zoom outline mode (this shows the area that will
          be included when zooming, displayed as dashed lines). Use
          cross-hair cursor when measuring distance.

2002-06-08  Anders Eriksson  <anders@umunet.org>

        * src/gerbv.c (motion_notify_event, expose_event): Don't
          redraw entire image when drawing zoom outline and measured
          distance. This makes the outline follow much more smoothly.
          The side effect in measure mode is that several measures
          may be visible simultaneously. I am not sure if this is
          a bug or a feature. :)

2002-06-08  Stefan Petersen  <spe@stacken.kth.se>

        * src/gerbv.c: Setting up a watch while running export_image.
        * configure.in: Adding a check for libpng when export_png enabled. 

2002-06-07  Anders Eriksson  <anders@umunet.org>

        * src/gerbv.c (expose_event): Center distance strings properly,
          get string height to properly space the two lines independant
          of the resolution (dpi). Minor cleanups.

2002-06-07  Stefan Petersen  <spe@stacken.kth.se>

        * src/draw.c, src/gerb_image.h, src/gerber.c: Now handles
          negative layer polarity (%LP%)! After fixing bug 557368 
          this was simple to add. Tested with files from PCB.

2002-06-06  Stefan Petersen  <spe@stacken.kth.se>

        * src/gerbv.c, src/gerbv_screen.h: Added "reload files", gerbv 
          rereads all loaded files and display them. Usefull if you have
          an external gerber manipulation tool.

2002-06-06  Anders Eriksson  <anders@umunet.org>

        * src/gerbv.c, src/gerbv_screen.h: Added a crude measurement tool,
          renamed screen.zstart_[xy] since they are now used for measure-
          ment also. To use this tool hold down <SHIFT> while pressing
          button 1 (the leftmost). This functionality still needs some work.

2002-06-06  Stefan Petersen  <spe@stacken.kth.se>

        * src/draw.c, src/gerb_image.h, src/gerber.c: Added counting and
          storing of number of corners in polygons, so drawing of polygons
          can use dynamically allocated memory. Hard coded array size gave
          horrible result with submitted file from David Cussans with a lot
          of corners in the polygons.


2002-06-05  Stefan Petersen  <spe@stacken.kth.se>

        * src/gerbv.c: Added check to autoscale so scale don't screw up
          everything.
        

2002-06-02  Stefan Petersen  <spe@stacken.kth.se>

        * src/gerb_image.h, src/gerber.c: Thanks to Stephen Adam I now know
          what %IC??*% means (Input Code) and have added it to the parser.
        

2002-05-18  Stefan Petersen  <spe@stacken.kth.se>

        * configure.in, acconfig.h, src/Makefile.am, src/gerbv.c,
          src/gerbv_screen.h, src/exportimage.[hc], CONTRIBUTORS: 
          Added "export image to PNG" contributed by Dino Ghilardi.
          Thanks! Currently not default, use --enable-exportpng when
          running configure.
        

2002-05-17  Stefan Petersen  <spe@stacken.kth.se>

        * src/gerbv.c, src/gerbv_screen.h: Split out the global
          screen variable and it's struct to simplify future 
          split of gerbv.c.

        * acconfig.h, configure.in, src/gerbv.c, scm_gerber.c:
          Prepared phase out of Guile by changing default to exclude
          Guile inclusion.Change flag disable-batch to enable-batch 
          during configure and changing the variable NO_GUILE to 
          GUILE_IN_USE.

        
2002-05-10  Stefan Petersen  <spe@stacken.kth.se>

        * src/gerb_image.*, src/gerber.*, src/gerbv.c: Moved verify_gerb
          to gerb_image and renamed it to gerb_image_verify so drill file
          parsing and gerber file parsing could split them. Done after 
          receiveing Excellon file without drillfile sizes (Innoveda/PADS
          Power PCB) from Dino Ghilardi.
        * src/gerb_file.c: Improved error reporting.
        

2002-05-08  Anders Eriksson  <anders@umunet.org>

        * src/gerbv.c (zoom_outline): Prevent division by zero by
        disallowing too small zoom areas in outline mode. Allocate a
        separate outline zoom color. Center outline zoom area instead
        of using upper left corner as translation points.

2002-05-08  Stefan Petersen  <spe@stacken.kth.se>

        * INSTALL: Changed gschem->gerbv
        * src/gerbv.c: Remember where we loaded file from last time and
          start file selection from there.

        
2002-05-07  Anders Eriksson  <anders@umunet.org>

        * src/gerbv.c (zoom_outline): Added zoom outline support and
        scaled zoom step (zoom 10% of current scale instead of a fixed
        number of 10). Some comments in old code. The outline drawing could
        probably be optimized quite a bit (it currently piggybacks on the
        expose event). With this functionality it is easier to note the
        excessive memory usage when zooming in too far.

-- Release 0.0.8 --
        
        
2002-05-05  Stefan Petersen  <spe@stacken.kth.se>

        * configure.in: Updated VERSION.
        * src/gerbv.c: If gerbv was started without any files loaded,
          the watch mouse pointer was running all the time.
        

2002-05-03  Anders Eriksson  <anders@umunet.org>

        * AUTHORS: Corrected my e-mail address

2002-05-02  Anders Eriksson  <anders@umunet.org>

        * src/gerbv.c: Made redraw_pixmap() and image2pixmap()
        interruptible by calling g_main_pending() at regular intervals and
        registering an idle function to redraw the pixmap at a later time
        if there are pending events to process. This partly fixes 550319.
          Also added the event to the data sent to the zoom function since
        this allows us to read the mouse position at the event generation
        and not at processing time which we used to do (giving a very
        confusing behaviour if we can't keep up with events).

2002-05-02  Stefan Petersen  <spe@stacken.kth.se>

        * src/draw.c: Now ovals are ovals and not ellypses.
          Closes bug 548099.
        * HACKING, AUTHORS, CONTRIBUTORS: Updated with more authors
          and contributors. Also extended HACKING to include ChangeLog
          and code format.
        * src/gerbv.c: Autoscale is more correct, though not completely
          perfect. Closes bug 550795.
        
2002-04-29  Anders Eriksson  <anders@umunet.org>

        * src/gerbv.c: Improved zoom. Now zooming around image center when
        zooming from menu and around mouse pointer when zooming using the
        mouse. There seems to be some (small) rounding error in the
        centering code, but it is very small. Closes 548128.

2002-04-27 Stefan Petersen (spe@stacken.kth.se)

        * src/gerbv.c: Number constants replaced with an enumeration
          type. Also error in zooming comments fixed.
        * man/gerbv.1.in: Added blurb about zooming.
        * src/gerber.c: Bug 549602 fixed so format statements are
          completely handled.


2002-04-27 Stefan Petersen (spe@stacken.kth.se)

        * src/gerbv.c: Changed name for all *open* functions to 
          *load*. Implemented "unload file" in right-click popup,
          which closes feature req. 548124.
        

2002-04-24 Stefan Petersen (spe@stacken.kth.se)

        * src/gerb_file.c: Fixed bug causing segfault when opening
          empty file (bug 548578).

        
2002-04-24 Stefan Petersen (spe@stacken.kth.se)

        * man/gerbv.1: Removed.
        * man/gerbv.1.in: Created, so configure can add version of 
          gerbv automagically. Also added blurb about right-click thing.
        * configure.in: man/gerbv.1 is created from man/gerbv.1.in.
        

2002-04-24 Stefan Petersen (spe@stacken.kth.se)

        * example/orcad/*: Added after submission from and with 
          permission from Dino Ghilardi.


2002-04-10 Stefan Petersen (spe@stacken.kth.se)

        * src/gerber.c: Fixed mq arcs so circles are circles and
          and width/height are correctly calculated. Closes bug
          #541089. Hopefully.

        
2002-04-09 Stefan Petersen (spe@stacken.kth.se)

        * src/gerber.c: Fixed draw direction of arcs reported in
          bug #541089. Not drawn D3 and VR1, and wrong size on some
          transistors, still open.
        

2002-04-03 Stefan Petersen (spe@stacken.kth.se)

        * src/gerber.c, src/gerber.h: Fixed some numerical
          constants in verify code.
        

2002-04-03 Stefan Petersen (spe@stacken.kth.se)

        * src/gerbv.c: Added color selection on layers.
        * TODO: Added zooming and gerber layers.

        
2002-02-10 Stefan Petersen (spe@stacken.kth.se)

        * src/draw.c: Added inclusion of string.h as pointed out by 
          Dan McMahill.
        

-- Release 0.0.7 --     

        
2002-02-03 Stefan Petersen (spe@stacken.kth.se)

        * src/draw.c: Fixed bugs in drawing primitive 6 and 7 after
          verification. The last primitives...
        * example/am-test/am-test.gbx: The verification suite for 
          aperture macros.
        
        
2002-01-06 Stefan Petersen (spe@stacken.kth.se)

        * src/amacro.c: Parser handles negative immediate values.
        * src/draw.c: Load of minor bugfixes after verification like 
          rotate points in the other direction, line wiidths constant,
          wrong indeces.
        * src/gerber.c: Rewrote parse_aperture_defintion to handle 
          aperture defintions without parameters.
        

2002-01-06 Stefan Petersen (spe@stacken.kth.se)

        * src/draw.c: All primitive macros are implemented (though not
          completely) and passed the MS-test; they compile. Now it's 
          verify, verify and verify.

        
2001-12-31 Stefan Petersen (spe@stacken.kth.se)

        * src/draw.c: Started to add functions to be able to draw
          aperture macros too. Some aperture macro primitives are 
          half way implemented, so the examples in the distribution
          should work. Though not 100% properly.
        
        
2001-12-30 Stefan Petersen (spe@stacken.kth.se)

        * src/amacro.[hc]: Added, even though I haven't executed 
          an aperture macro program yet. But parsing seems stable.
        * src/gerb_image.[hc], gerber.c, src/Makefile.am: Calls 
          and keeps track of parsing of aperture macros.
        * doc/aperturemacro.txt: simple text on the "program code"
          generated when parsing aperture macros.


2001-12-29 Andreas Andersson (e92_aan@e.kth.se)

        * src/gerb_file.c:
          Fixed gerb_fgetstring() to not write after the end of the
          allocated array.
        * src/gerber.c:
          Removed small memory leak in parse_aperture_definition()


2001-12-29 Andreas Andersson (e92_aan@e.kth.se)

        * src/drill.c:
          Autodetection routine changed back to original style to allow
          special cases needed with output from some CAD systems.
        * src/gerb_file.c:
          Error check for mmap() added to stop gerbv from segdumping
          when trying to open a directory instead of a file.


2001-12-29 Stefan Petersen (spe@stacken.kth.se)

        * src/gerb_file.[hc], src/gerber.c: Added function 
          gerb_fgetstring and used it.

        
-- Release 0.0.6 --     

        
2001-12-14 Stefan Petersen (spe@stacken.kth.se)

        * src/draw.c : Removed gdk_gc_set_line_attribute when drawing
          a point.
        * src/gerbv.c: Added autoscaling and autocentering, both as
          a menu option (Zoom/Fit) and when loading a file.

        
2001-12-11 Stefan Petersen (spe@stacken.kth.se)

        * src/gerbv.c : Removed prelighting on buttons and changed
          the "random function" creating colors. Also fixed "clear 
          all" remaining after the pan speedup rewrite.

        
2001-12-10 Stefan Petersen (spe@stacken.kth.se)

        * src/gerbv.c : Forgot to check if we had any pixmap to draw.

        
2001-12-09 Stefan Petersen (spe@stacken.kth.se)

        * src/gerber.c: Fixed small bug in min/max calculation
          which caused big problems.
        * src/gerbv.c: Major rewrite of panning code giving major
          improvements in screen update speed.
        

2001-12-07 Stefan Petersen (spe@stacken.kth.se)

        * src/draw.[hc], src/gerbv.c : Pseudo optimized drawing.
        * src/gerb_file.c, src/gerbv.c: Fixed bug causing segfault
          when file didn't exist (oops) and pushed error messages
          out of gerb_file.c. And if a file (of many) given at 
          commandline doesn't exist, the next file is tried instead 
          of halting.

        
2001-12-06 Stefan Petersen (spe@stacken.kth.se)

        * src/drill.c, src/gerb_image.c, src/gerber.c, src/gerbv.c:
          Exchanged bzero with memset for further portability.
        * scheme/Makefile.am: gerb-debug.scm gets installed too.
        

2001-12-06 Andreas Andersson (e92_aan@e.kth.se)

        * src/drill.[hc]:
          Very minor change to allow tool number 0.


2001-12-03 Stefan Petersen (spe@stacken.kth.se)

        * src/Makefile.am, src/color.c, src/gerber.c, src/scm_gerber.c:
          Turned on -Wall and cleaned up after it.

        
2001-12-03 Stefan Petersen (spe@stacken.kth.se)

        * src/drill.h, src/gerber.h, src/gerbv.c:
          Fixed bug caused by last minute namechange of 
          gerb_file.[hc].
        * src/gerb_file.[hc]: Added functions gerb_fgetint and
          gerb_fgetdouble.
        * src/drill.c, src/gerber.c: Utilize the new file read
          functions.
        
        
2001-12-02 Stefan Petersen (spe@stacken.kth.se)

        * src/gerb_file.[hc], src/drill.[hc], src/gerber.[hc], gerbv.c:
          Changed method of file IO from fgetc to mmap. Speed increase 
          up to 3 times noted (loading all of jj's file at ones).

        
2001-12-02 Stefan Petersen (spe@stacken.kth.se)

        * src/drill.c: drill_file_p recoded so it seems to work better.
        * src/gerbv.c: Removed and cleaned up "open file" code.
        * src/gerbv.c, src/color.c, src/color.h: Fixed the whole mess
          with colors. Now colors doesn't set any limits on how many files
          you can load. It also checks that you don't give too many files
          to the program.
        

2001-12-02 Andreas Andersson (e92_aan@e.kth.se)

        * src/gerbv.c:
          Changed radiobuttons to togglebuttons, redraw_pixmap() now shows
          all switched on images. Slight changes to the zoom/translate code
          (it still doesn't work as intended, though). Added mouse commmands
          for zooming without scrollwheel. screen.scale no longer goes down
          to 0 when zooming out.
        * src/draw.h, src/draw.c:
          Floating point calculations that are converted to ints for
          display are now rounded to the nearest int rather than always
          truncated down (or was it up?) Macro round(x) added to make that
          prettier. Removed minor stuff that caused warnings with -Wall
          flag to gcc.


2001-11-27 Andreas Andersson (e92_aan@e.kth.se)

        * src/gerbv.c:
          Added autodetection of file type.
        * src/drill.c:
          Corrected stupid bug in autodetection.


2001-11-27 Andreas Andersson (e92_aan@e.kth.se)

        * src/drill.h, src/drill.c:
          Added drill_file_p(); which checks whether a file could
          be a drill file or not.


2001-11-26 Stefan Petersen (spe@stacken.kth.se)

        * configure.in: Now --data works when running ./configure.
          A patch from Wojciech Kazubski <wk@ire.pw.edu.pl>


2001-11-26 Andreas Andersson (e92_aan@e.kth.se)

        * src/drill.c:
          Coordinate parsing now works on coordinates with decimal points.
          More M codes and some G codes recognized. Most importantly
          absolute/incremental mode and zero setting could work, though
          it hasn't been properly tested yet.


2001-11-23 Stefan Petersen (spe@stacken.kth.se)

        * src/gerb_image.h, src/draw.c, src/gerber.c, src/scm_gerber.c:
          Are now able to parse and display polyogon area fill codes.

        
2001-11-21 Andreas Andersson (e92_aan@e.kth.se)

        * src/drill.c:
          The format guessing code now guesses right for
          one more format.
          More M codes recognized (and later ignored).

        
2001-11-20 Stefan Petersen (spe@stacken.kth.se)

        * src/scm_gerber.c: Backend didn't receive the last
          entry in the netlist due to bad loop constraint.
        * src/gerber.c: Made sure angles always are positive when
          calculating multi quadrant ones.
        * src/gerber.c: Improved error detection by checking that
          all part of an image is there.
        * src/gerber.c: Fix for EagleCad caused other Gerber files
          to fail. Only D-code 1-3 on a line should also be considered
          as a change.
        
        
2001-11-15 Stefan Petersen (spe@stacken.kth.se)

        * src/gerbv.c: Tooltips over radio buttons with name
          of loaded file.

        
-- Release 0.0.5 --     

        
2001-11-14 Stefan Petersen (spe@stacken.kth.se)

        * src/gerbv.c: Changed speed key for zooming in to
          Alt-O.
        * configure.in: Changed version number for release.
        
        
2001-11-09 Stefan Petersen (spe@stacken.kth.se)

        * src/gerb_image.[hc]: Added.
        * src/drill.[hc], src/gerber.[hc], src/scm_gerber.[hc]:
          Changed to utilize the new "class", gerb_image.

        
2001-11-07 Stefan Petersen (spe@stacken.kth.se)

        * src/draw.c, src/gerber.c: Implemented multi quadrant arcs.
          Calculated with a separate function; should be able to be
          combined with single quadrant calculations. Not properly 
          tested since I need better examples.
        
        
2001-11-06 Andreas Andersson (e92_aan@e.kth.se)

        * src/drill.h, src/drill.c:
          parse_drillfile() now ignores unstandard text in headers.
          Also, it now returns the actual unit used (it used to return
          the unit of the input file).
          Minor fixes, mostly moved stuff around.

2001-11-03 Stefan Petersen (spe@stacken.kth.se)

        * src/drill.c, src/scm_gerber.c: Fixed bug causing backend
          first not to generate aperture list and then barfing when
          trying.

        
2001-11-03 Stefan Petersen (spe@stacken.kth.se)

        * src/gerbv.c: Added command line -d|--drill support 
          for drill files both in graphical mode and batch mode.
          Though are drill file tool/apertures not properly handled
          by ->scheme converter.
        * man/gerbv.1: Changed man page to reflect the new switches.
        
2001-11-03 Stefan Petersen (spe@stacken.kth.se)

        * src/gerber.[hc]: Cleaned up code after latest hack.
        * src/scm_gerber.c: Changed format of list delivered to
          the backend; no delta center points. Now it's all calculated
          center points and angles.
        * scheme/gerb-ps.scm: Accept the new list, but doesn't do anything
          with it yet.

        
2001-11-03 Stefan Petersen (spe@stacken.kth.se)

        * src/gerber.c: Inserted check for undefined apertures that
          was earlier removed.

        
2001-11-02 Stefan Petersen (spe@stacken.kth.se)

        * src/gerber.h, src/gerber.c, src/draw.c: Now almost
          all calculation for circles is done when parsing and
          not when (re)drawing.
        * src/gerbv.c: Removed two unnecessary defines.
        
        
2001-10-31 Stefan Petersen (spe@stacken.kth.se)

        * src/gerbv.c: Added zooming with scroll wheel on mouse.
        * README: Added info on how to configure XFree86 for scroll mouse.

        
2001-10-28 Stefan Petersen (spe@stacken.kth.se)

        * src/gerber.[hc]: Fixed bug causing parser to reports
          points with wrong aperture. Pointed out by Dan Christian.
        

2001-10-30 Andreas Andersson (e92_aan@e.kth.se)

        * src/drill.c, src/gerber.h, src/gerber.c
          Moved new_image() to the correct place

        
2001-10-28 Andreas Andersson (e92_aan@e.kth.se)

        * src/Makefile.am
          Added drill.c to SOURCES since it seems to work well enough
          for some testing.
        * src/drill.c
          Added an input file format guessing function.
          Some kludges to get around scaling problems.

        * src/draw.c, src/gerber.h, src/gerber.c, src/scm_gerber.c:
          aperture array is now full size and array index is very
          simple.

        * src/gerber.[hc]: EagleCad generates broken Gerber.
          I kindly detect and then tries to run as nothing 
          happened. Disable kludge with commenting out 
          EAGLECAD_KLUDGE in src/gerber.h.
          This was pointed out to me by Dan Christian and
          later confirmed by Fredrik Jonsson sent me some
          examples. Thanks guys!
        * AUTHORS/CONTRIBUTORS: Added latest bunch of contributing
          people.
        * configure.in: Updated version to 0.0.4 before release.

        * src/draw.[hc]: Added. Extracted drawing functions from
          gerbv.c.

          Also minor clean ups. Fixed #def's of Guile support.

        * example/*: Cleaned out numpres.pcb.* to a separate dir
          and added a example received from Joachim Jansen on
          separate aperture files.

        * gerbv.c: Changed how cw and ccw is handled when drawing
          arcs to avoid swapping of start and stop points.
        * gerbv.c: Red dots at "aperture macros wanna-be's" scale
          with ordinary scale, so they don't disappear when scaling
          around.

        
2001-10-09 Stefan Petersen (spe@stacken.kth.se)

        * gerber.h, gerber.c: Added 'D' as possible Format
          Statement after patches from Uwe Bonnes
          <bon@elektron.ikp.physik.tu-darmstadt.de>. Thanks!
        * scm_gerber.c: Broke out omit_zeros_t to scm type
          conversion and added 'explicit to this type.

        * configure.in: fixed bug when testing for opt_backend_dir
          causing configure to fail at least on Solaris.
        * INSTALL: updated with info now that automake's in use.

        
2001-09-02 Stefan Petersen (spe@stacken.kth.se)

        * build-release, rebuild-conf: missing files when running
          automake are now copied instead of linked. Thanks
          Dan <mcmahill@mtl.mit.edu> for reporting this.

        * Splitted AUTHORS to AUTHORS and CONTRIBUTORS
        * src/gerb-ps.scm: removed 
        * build_release uses anonymous cvs from sourceforge
          to build the release.
        * src/scm_gerber.c, src/gerbv.c:
          Now the scheme backend receives the name of the parsed file
        * scheme/gerb-ps.scm: Utilizes the above feature by creating output
          filename by prepending input filename with ".ps"
