28 * Cursors and icons are stored in a global heap block, with the
31 * CURSORICONINFO info;
35 * The bits structures are in the format of a device-dependent bitmap.
37 * This layout is very sub-optimal, as the bitmap bits are stored in
38 * the X client instead of in the server like other bitmaps; however,
39 * some programs (notably Paint Brush) expect to be able to manipulate
40 * the bits directly :-(
