Log:
- Rework NtGdiStretchBlt into GreStretchBltMask function, which provides stretch blitting
with mask support.
- Add NtGdiStretchBlt as a simple forwarder to the internal GreStretchBltMask helper.
- Based on a patch by Evgeniy Boltik.
- Some optimisation issues could still be solved as Timo suggested.
See issue #4294 for more details.
