* 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 :-(
