Vladimir Serbinenko 1289b71437 NEVERHOOD: Fix crash on expiring surfaces.
We postpone actual drawing until the frame finishes. At this point some of
the surfaces might have been freed and the pointers are no longer valid.
Use reference counting to ensure that queue surfaces are still valid

Thanks to -=CHE@TER=- for reporting and providing the triggering save
and instructions.
