[PATCH 1/2] render: Always store client clip as a region

This does have one semantic change. FixesCreateRegionFromPicture used to
throw BadImplementation if you tried to create a region from a picture
with no client clip. I changed that to BadMatch here since that more
honestly describes what's going on.
