Always bind a new texture to unit 1 when necessary

Browse source 
The special handling for texture unit 1 caught the case where unit
1 was changed for transient purposes, but didn't properly handle
the case where the actual non-transient texture was different between
two materials with no transient binding in between.

If the actual texture has changed when flushing, mark unit 1 as dirty
and needing a rebind.
