Enrico Weigelt, metux IT consult ef62929f58 treewide: NULL-protect ScreenRec->DestroyPixmap() calls 
Right now, we're assuming that even when deep nesting involved, the proc
vector is always set to a valid function. One the one hand it requires
extra dummy procs in some cases, OTOH it's making upcoming refactoring
of the code flow unnecessarily complex.

The big plot (of subsequent commits) is splitting out the extension's
(and possibly subsystem's) special logic out of the wrapping chain and
let them be executed independently from the DDX/drivers - when applicable
even only when the pixmap is really destroyed (not just unref'ed).
(At some later point, it might even become be actually a valid situation
that DestroyPixmap vector really being NULL.)
