[WIN32K]
- Set NULL owner to copied bitmap when creating indirect icons - Rewrite UserDrawIconEx, inspired from wine code - fix palette creation for 16 bits DIB - Always assign a palette to bitmap created with BITMAP_CopyBitmap and IntCreateCompatibeBitmap. [USER32] - Use DIB section when creating icons - Use something called "header" Now mode switching is almost glitchless. svn path=/branches/reactos-yarotows/; revision=47140
