Log:
[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.
