- Allocate bitmaps as kernel sections, instead of from paged pool, like it's done in windows. - Fix SURFACE_Cleanup. It was only freeing the memory for API_BITMAPs. If memory was allocated by a driver it never got freed. - Add BMF_RLE_HACK flag to free decompressed RLE bits - Support FL_ZERO_MEMORY in EngAllocSectionMem - Set SURFOBJ::iType when creating a surface svn path=/branches/reactos-yarotows/; revision=47606
