46 /* Notes on the implementation
48 * The implementation is based on dynamically resizable arrays of points and
49 * flags. I dithered for a bit before deciding on this implementation, and
50 * I had even done a bit of work on a linked list version before switching
51 * to arrays. It's a bit of a tradeoff. When you use linked lists, the
52 * implementation of FlattenPath is easier, because you can rip the
53 * PT_BEZIERTO entries out of the middle of the list and link the
54 * corresponding PT_LINETO entries in. However, when you use arrays,
55 * PathToRegion becomes easier, since you can essentially just pass your array
56 * of points to CreatePolyPolygonRgn. Also, if I'd used linked lists, I would
57 * have had the extra effort of creating a chunk-based allocation scheme
58 * in order to use memory effectively. That's why I finally decided to use
59 * arrays. Note by the way that the array based implementation has the same
60 * linear time complexity that linked lists would have since the arrays grow
63 * The points are stored in the path in device coordinates. This is
64 * consistent with the way Windows does things (for instance, see the Win32
65 * SDK documentation for GetPath).
67 * The word "stroke" appears in several places (e.g. in the flag
68 * GdiPath.newStroke). A stroke consists of a PT_MOVETO followed by one or
69 * more PT_LINETOs or PT_BEZIERTOs, up to, but not including, the next
70 * PT_MOVETO. Note that this is not the same as the definition of a figure;
71 * a figure can contain several strokes.
