25 /*
26 * Theory:
27 *
28 * 32-bit cursors and icons are stored in the server.
29 *
30 * 16-bit cursors and icons are stored in a global heap block, with the
31 * following layout:
32 *
33 * CURSORICONINFO info;
34 * BYTE[] ANDbits;
35 * BYTE[] XORbits;
36 *
37 * The bits structures are in the format of a device-dependent bitmap.
38 *
39 * This layout is very sub-optimal, as the bitmap bits are stored in
40 * the X client instead of in the server like other bitmaps; however,
41 * some programs (notably Paint Brush) expect to be able to manipulate
42 * the bits directly :-(

2787 * BUGS
2788 * Only Windows NT 4.0 supports the LR_COPYRETURNORG flag for bitmaps,
2789 * all other versions (95/2000/XP have been tested) ignore it.
2790 *
2791 * NOTES
2792 * If LR_CREATEDIBSECTION is absent, the copy will be monochrome for
2793 * a monochrome source bitmap or if LR_MONOCHROME is present, otherwise
2794 * the copy will have the same depth as the screen.
2795 * The content of the image will only be copied if the bit depth of the
2796 * original image is compatible with the bit depth of the screen, or
2797 * if the source is a DIB section.
2798 * The LR_MONOCHROME flag is ignored if LR_CREATEDIBSECTION is present.
