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