Browse source 
- pass COLORADJUSTMENT to IntEngStretchBlt
- IntEngStretchBlt, EngStretchBltROP, DrvStretchBltROP always use a source, ASSERT that
- annotate pbrDefaultBrush and psurfDefaultBitmap as _Notnull_
- Don't use uninitialized psoInput in EngStretchBltROP
- Use trivial CLIPOBJ instead of NULL in IntEngStretchBlt
- Always pass a source surface to EngStretchBltROP
