* Cursor and icon support

/*
* 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 :-(
