  27  * http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnwui/html/msdn_icons.asp
  28  *
  29  * Cursors and icons are stored in a global heap block, with the
  30  * following layout:
  31  *
  32  * CURSORICONINFO info;
  33  * BYTE[]         ANDbits;
  34  * BYTE[]         XORbits;
  35  *
  36  * The bits structures are in the format of a device-dependent bitmap.
  37  *
  38  * This layout is very sub-optimal, as the bitmap bits are stored in
  39  * the X client instead of in the server like other bitmaps; however,
  40  * some programs (notably Paint Brush) expect to be able to manipulate
  41  * the bits directly :-(
  42  *
  43  * FIXME: what are we going to do with animation and color (bpp > 1) cursors ?!

1049  *
1050  * BUGS
1051  *
1052  *  - The provided bitmaps are not resized!
1053  *  - The documentation says the lpXORbits bitmap must be in a device
1054  *    dependent format. But we must still resize it and perform depth
1055  *    conversions if necessary.
1056  *  - I'm a bit unsure about the how the 'device dependent format' thing works.
1057  *    I did some tests on windows and found that if you provide a 16bpp bitmap
1058  *    in lpXORbits, then its format but be 565 RGB if the screen's bit depth
1059  *    is 16bpp but it must be 555 RGB if the screen's bit depth is anything
1060  *    else. I don't know if this is part of the GDI specs or if this is a
1061  *    quirk of the graphics card driver.
1062  *  - You may think that we check whether the bit depths match or not
1063  *    as an optimization. But the truth is that the conversion using
1064  *    CreateDIBitmap does not work for some bit depth (e.g. 8bpp) and I have
1065  *    no idea why.
1066  *  - I'm pretty sure that all the things we do in CreateIcon should
1067  *    also be done in CreateIconIndirect...
