| * Theory: |
| * |
| * 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 :-( |
