/*
 * Theory:
 *
 * http://www.microsoft.com/win32dev/ui/icons.htm
 *
 * Cursors and icons are stored in a global heap block, with the
 * following layout:
 *
 * CURSORICONINFO info;
 * BYTE[]         ANDbits;
 * BYTE[]         XORbits;
 *
 * The bits structures are in the format of a device-dependent bitmap.
 *
 * This layout is very sub-optimal, as the bitmap bits are stored in
 * the X client instead of in the server like other bitmaps; however,
 * some programs (notably Paint Brush) expect to be able to manipulate
 * the bits directly :-(
 *
 * FIXME: what are we going to do with animation and color (bpp > 1) cursors ?!
