29 * Cursors and icons are stored in a global heap block, with the
32 * CURSORICONINFO info;
36 * The bits structures are in the format of a device-dependent bitmap.
38 * This layout is very sub-optimal, as the bitmap bits are stored in
39 * the X client instead of in the server like other bitmaps; however,
40 * some programs (notably Paint Brush) expect to be able to manipulate
41 * the bits directly :-(
43 * FIXME: what are we going to do with animation and color (bpp > 1) cursors ?!
