  11  * Theory:
  12  *
  13  * http://www.microsoft.com/win32dev/ui/icons.htm
  14  *
  15  * Cursors and icons are stored in a global heap block, with the
  16  * following layout:
  17  *
  18  * CURSORICONINFO info;
  19  * BYTE[]         ANDbits;
  20  * BYTE[]         XORbits;
  21  *
  22  * The bits structures are in the format of a device-dependent bitmap.
  23  *
  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 :-(
  28  *
  29  * FIXME: what are we going to do with animation and color (bpp > 1) cursors ?!
