5 *
6 * Copyright 1998 Sander van Leeuwen (sandervl@xs4all.nl) (OS/2 Port)
7 *

16 * Theory:
17 *
18 * http://www.microsoft.com/win32dev/ui/icons.htm
19 *
20 * Cursors and icons are stored in a global heap block, with the
21 * following layout:
22 *
23 * CURSORICONINFO info;
24 * BYTE[] ANDbits;
25 * BYTE[] XORbits;
26 *
27 * The bits structures are in the format of a device-dependent bitmap.
28 *
29 * This layout is very sub-optimal, as the bitmap bits are stored in
30 * the X client instead of in the server like other bitmaps; however,
31 * some programs (notably Paint Brush) expect to be able to manipulate
32 * the bits directly :-(
33 *
34 * FIXME: what are we going to do with animation and color (bpp > 1) cursors ?!
35 *
36 **************************************************************************************************
37 *
38 * TODO: Scaling of system cursors (store them as resources in user32 instead of using PM pointers)
39 * TODO: We use the hColorBmp member of the CURSORICONINFO structure to store the PM cursor handle
40 * Might mess up PaintBrush (see above)
