10 /*
11 * Theory:
12 *
13 * http://www.microsoft.com/win32dev/ui/icons.htm
14 *
15 * Cursors and icons are stored in a global heap block, with the
16 * following layout:
17 *
18 * CURSORICONINFO info;
19 * BYTE[] ANDbits;
20 * BYTE[] XORbits;
21 *
22 * The bits structures are in the format of a device-dependent bitmap.
23 *
24 * This layout is very sub-optimal, as the bitmap bits are stored in
25 * the X client instead of in the server like other bitmaps; however,
26 * some programs (notably Paint Brush) expect to be able to manipulate
27 * the bits directly :-(
28 *
29 * FIXME: what are we going to do with animation and color (bpp > 1) cursors ?!

1146 * - The provided bitmaps are not resized!
1147 * - The documentation says the lpXORbits bitmap must be in a device
1148 * dependent format. But we must still resize it and perform depth
1149 * conversions if necessary.
1150 * - I'm a bit unsure about the how the 'device dependent format' thing works.
1151 * I did some tests on windows and found that if you provide a 16bpp bitmap
1152 * in lpXORbits, then its format but be 565 RGB if the screen's bit depth
1153 * is 16bpp but it must be 555 RGB if the screen's bit depth is anything
1154 * else. I don't know if this is part of the GDI specs or if this is a
1155 * quirk of the graphics card driver.
1156 * - You may think that we check whether the bit depths match or not
1157 * as an optimization. But the truth is that the conversion using
1158 * CreateDIBitmap does not work for some bit depth (e.g. 8bpp) and I have
1159 * no idea why.
1160 * - I'm pretty sure that all the things we do in CreateIcon should
1161 * also be done in CreateIconIndirect...
