25 * Theory:
26 *
27 * http://www.microsoft.com/win32dev/ui/icons.htm
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 ?!

1147 * CreateIcon (USER32.@)
1148 *
1149 * Creates an icon based on the specified bitmaps. The bitmaps must be
1150 * provided in a device dependent format and will be resized to
1151 * (SM_CXICON,SM_CYICON) and depth converted to match the screen's color
1152 * depth. The provided bitmaps must be top-down bitmaps.
1153 * Although Windows does not support 15bpp(*) this API must support it
1154 * for Winelib applications.
1155 *
1156 * (*) Windows does not support 15bpp but it supports the 555 RGB 16bpp
1157 * format!
1158 *
1159 * BUGS
1160 *
1161 * - The provided bitmaps are not resized!
1162 * - The documentation says the lpXORbits bitmap must be in a device
1163 * dependent format. But we must still resize it and perform depth
1164 * conversions if necessary.
1165 * - I'm a bit unsure about the how the 'device dependent format' thing works.
1166 * I did some tests on windows and found that if you provide a 16bpp bitmap
1167 * in lpXORbits, then its format but be 565 RGB if the screen's bit depth
1168 * is 16bpp but it must be 555 RGB if the screen's bit depth is anything
1169 * else. I don't know if this is part of the GDI specs or if this is a
1170 * quirk of the graphics card driver.
1171 * - You may think that we check whether the bit depths match or not
1172 * as an optimization. But the truth is that the conversion using
1173 * CreateDIBitmap does not work for some bit depth (e.g. 8bpp) and I have
1174 * no idea why.
1175 * - I'm pretty sure that all the things we do in CreateIcon should
1176 * also be done in CreateIconIndirect...
