[jgardou] 48483: [WIN32K] - work directly with bitmap bits when alpha blending icons. This is permitted, those are API bitmaps. - Do not create a stretched copy of source surface in EngAlphaBlend, handle stretching in DIB functions. - Do so. - Simplify DIB alpha blending for 24 and 32 bpp, implement generic alpha blend support for other depth.

Log:
[WIN32K]
- work directly with bitmap bits when alpha blending icons. This is permitted, those are
API bitmaps.
- Do not create a stretched copy of source surface in EngAlphaBlend, handle stretching
in DIB functions.
- Do so.
- Simplify DIB alpha blending for 24 and 32 bpp, implement generic alpha blend support
for other depth.
