|
|
* 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 :-(
|
|
*
|
|
* FIXME: what are we going to do with animation and color (bpp > 1) cursors ?!

|

* Success: handle to an icon

|

*
|
|
* BUGS
|
|
*
|
|
* - The provided bitmaps are not resized!
|
|
* - The documentation says the lpXORbits bitmap must be in a device
|
|
* dependent format. But we must still resize it and perform depth
|
|
* conversions if necessary.
|
|
* - I'm a bit unsure about the how the 'device dependent format' thing works.
|
|
* I did some tests on windows and found that if you provide a 16bpp bitmap
|
|
* in lpXORbits, then its format but be 565 RGB if the screen's bit depth
|
|
* is 16bpp but it must be 555 RGB if the screen's bit depth is anything
|
|
* else. I don't know if this is part of the GDI specs or if this is a
|
|
* quirk of the graphics card driver.
|
|
* - You may think that we check whether the bit depths match or not
|
|
* as an optimization. But the truth is that the conversion using
|
|
* CreateDIBitmap does not work for some bit depth (e.g. 8bpp) and I have
|
|
* no idea why.
|
|
* - I'm pretty sure that all the things we do in CreateIcon should
|
|
* also be done in CreateIconIndirect...
