25 * Theory:
26 *
27 * http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnwui/html/msdn_icons.asp
28 *
29 * Cursors and icons are stored in a global heap block, with the
30 * following layout:
31 *
32 * CURSORICONINFO info;
33 * BYTE[] ANDbits;
34 * BYTE[] XORbits;
35 *
36 * The bits structures are in the format of a device-dependent bitmap.
37 *
38 * This layout is very sub-optimal, as the bitmap bits are stored in
39 * the X client instead of in the server like other bitmaps; however,
40 * some programs (notably Paint Brush) expect to be able to manipulate
41 * the bits directly :-(
42 *
43 * FIXME: what are we going to do with animation and color (bpp > 1) cursors ?!

1103 *
1104 * - The provided bitmaps are not resized!
1105 * - The documentation says the lpXORbits bitmap must be in a device
1106 * dependent format. But we must still resize it and perform depth
1107 * conversions if necessary.
1108 * - I'm a bit unsure about the how the 'device dependent format' thing works.
1109 * I did some tests on windows and found that if you provide a 16bpp bitmap
1110 * in lpXORbits, then its format but be 565 RGB if the screen's bit depth
1111 * is 16bpp but it must be 555 RGB if the screen's bit depth is anything
1112 * else. I don't know if this is part of the GDI specs or if this is a
1113 * quirk of the graphics card driver.
1114 * - You may think that we check whether the bit depths match or not
1115 * as an optimization. But the truth is that the conversion using
1116 * CreateDIBitmap does not work for some bit depth (e.g. 8bpp) and I have
1117 * no idea why.
1118 * - I'm pretty sure that all the things we do in CreateIcon should
1119 * also be done in CreateIconIndirect...
