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