  16  * The following is a graphics benchmark for the Commodore Amiga.
  17  * It performs several graphics and Intuition ( Amiga's user interface )
  18  * tasks. Some of the tests take some time, so be patient! There is a
  19  * nice punch at the end.
  20  *
  21  * Here are the results: ( ran as 1> amigademo > raw:file )
  22  *
  23  *  Doing point test in a full-screen window
  24  * Write pixel 640*200 took 31.5   Readpixel   640*200 took 23.1
  25  * Move        640*200 took 6.8    Control     640*200 took 0.9
  26  * Now doing point test directly to screen rastport
  27  * Write pixel 640*200 took 23.7   Readpixel   640*200 took 15.4
  28  * Move        640*200 took 6.8    Control     640*200 took 0.9
  29  * Block clear blitter 1:6.9 CPU 20.0
  30  * Block test in a full-screen window
  31  * Set 32K 10.2 Copy 14.7 Complement 14.7
  32  * Block test directly to screen rastport
  33  * Set 32K 10.1 Copy 14.4 Complement 14.3
  34  * Line test in window
  35  * Offset 0 result:10.5
  36  * Offset 1 result:10.6
  37  * Offset 20 result:10.5
  38  * Offset 100 result:10.4
