Log:
[WIN32K]
- Create default hatch brush bitmaps on win32k init
- After creating a PDEV fill the fields in the ahsurf array that are not filled by the
driver with these bitmaps
- don't create a new bitmap when a hatch brush is created, instead only store the
style and use the related bitmap from the PDEV when realizing the brush.
- Fix the palette of DIB brushes, when realizing the brush
- Don't leak the bitmaps for DIB brushes in BRUSH_Cleanup
