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