[fireball] 42333: - Handle case when RosGdiSetDeviceClipping is being called without rects at all (with a respective DPRINT1). - Use combined clipping object everywhere to ensure drawing happens only in allowed rectangle, see arwinss nr. 15. As a side effect, it fixes FireFox and other apps which would corrupt memory if trying to blit to area outside of DC. - Enable commented out XLATE object creation in GreStretchBltMask. Start menu icons now get masked properly too, but still are black.

Log:
- Handle case when RosGdiSetDeviceClipping is being called without rects at all (with a
respective DPRINT1).
- Use combined clipping object everywhere to ensure drawing happens only in allowed
rectangle, see arwinss nr. 15. As a side effect, it fixes FireFox and other apps which
would corrupt memory if trying to blit to area outside of DC.
- Enable commented out XLATE object creation in GreStretchBltMask. Start menu icons now
get masked properly too, but still are black.
