25 * Theory:
26 *
27 * Cursors and icons are stored in a global heap block, with the
28 * following layout:
29 *
30 * CURSORICONINFO info;
31 * BYTE[] ANDbits;
32 * BYTE[] XORbits;
33 *
34 * The bits structures are in the format of a device-dependent bitmap.
35 *
36 * This layout is very sub-optimal, as the bitmap bits are stored in
37 * the X client instead of in the server like other bitmaps; however,
38 * some programs (notably Paint Brush) expect to be able to manipulate
39 * the bits directly :-(
