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 ?!
