25 /*
26 * Theory:
27 *
28 * 32-bit cursors and icons are stored in the server.
29 *
30 * 16-bit cursors and icons are stored in a global heap block, with the
31 * following layout:
32 *
33 * CURSORICONINFO info;
34 * BYTE[] ANDbits;
35 * BYTE[] XORbits;
36 *
37 * The bits structures are in the format of a device-dependent bitmap.
38 *
39 * This layout is very sub-optimal, as the bitmap bits are stored in
40 * the X client instead of in the server like other bitmaps; however,
41 * some programs (notably Paint Brush) expect to be able to manipulate
42 * the bits directly :-(
