Ulrich Weigand d4663668b8 Changed DC members w.hVisRgn, w.hClipRgn, amd w.hGCClipRgn to 
coordinates relative to the device, not the DC origin. This is
necessary to correctly implement GetClipRgn16 and InquireVisRgn.
SelectVisRgn also expects region in device-relative coordinates.
Adapted the rest of Wine to this coordinate change.
Implemented ExtSelectClipRgn.
