35 * Data returned by GdipGetRegionData (for rectangle based regions)
36 * looks something like this:
38 * struct region_data_header
40 * DWORD size; size in bytes of the data - 8.
41 * DWORD magic1; probably a checksum.
42 * DWORD magic2; always seems to be 0xdbc01001 - version?
43 * DWORD num_ops; number of combining ops * 2
46 * Then follows a sequence of combining ops and RECTFs.
48 * Combining ops are just stored as their CombineMode value.
50 * Each RECTF is preceded by the DWORD 0x10000000. An empty rect is
51 * stored as 0x10000002 (with no following RECTF) and an infinite rect
52 * is stored as 0x10000003 (again with no following RECTF).
54 * The combining ops are stored in the reverse order to the RECTFs and in the
55 * reverse order to which the region was constructed.
57 * When two or more complex regions (ie those with more than one rect)
58 * are combined, the combining op for the two regions comes first,
59 * then the combining ops for the rects in region 1, followed by the
60 * rects for region 1, then follows the combining ops for region 2 and
61 * finally region 2's rects. Presumably you're supposed to use the
62 * 0x10000000 rect header to find the end of the op list (the count of
63 * the rects in each region is not stored).
65 * When a simple region (1 rect) is combined, it's treated as if a single rect
