[PATCH 3/3] [v2] gdi32: Adjust destination coordinates in some special cases.

[Akihiro Sagawa]

When the source rectangle needs to flip and it doesn't fit in the source
device area, the destination image is flipped but the destination area isn't
flipped.
GdiAlphaBlend doesn't support mirroring, the above isn't applicable.
