Michel Dänzer 1ca096d5e0 EXA: Track source/mask pixmaps more explicitly for Composite fallback regions. ...

In particular, make sure pExaScr->src/maskPix are cleared when the
corresponding pictures aren't associated with drawables, i.e. solid or gradient
pictures. Without this, we would in some cases associate the source/mask region
with unrelated pixmaps from previous Composite fallbacks, resulting in random
corruption.
