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

 *		CreateIcon (USER32.@)
 *
 *  Creates an icon based on the specified bitmaps. The bitmaps must be
 *  provided in a device dependent format and will be resized to

 *  depth. The provided bitmaps must be top-down bitmaps.
 *  Although Windows does not support 15bpp(*) this API must support it
 *  for Winelib applications.
 *
 *  (*) Windows does not support 15bpp but it supports the 555 RGB 16bpp
 *      format!
 *
 * BUGS
 *
 *  - The provided bitmaps are not resized!
 *  - The documentation says the lpXORbits bitmap must be in a device
 *    dependent format. But we must still resize it and perform depth
 *    conversions if necessary.
 *  - I'm a bit unsure about the how the 'device dependent format' thing works.
 *    I did some tests on windows and found that if you provide a 16bpp bitmap
 *    in lpXORbits, then its format but be 565 RGB if the screen's bit depth
 *    is 16bpp but it must be 555 RGB if the screen's bit depth is anything
 *    else. I don't know if this is part of the GDI specs or if this is a
 *    quirk of the graphics card driver.
 *  - You may think that we check whether the bit depths match or not
 *    as an optimization. But the truth is that the conversion using
 *    CreateDIBitmap does not work for some bit depth (e.g. 8bpp) and I have
 *    no idea why.
 *  - I'm pretty sure that all the things we do in CreateIcon should
 *    also be done in CreateIconIndirect...
