xlib: Use image fallback for GOOD/BEST filters

Browse source 
Fallback is not used if the symbols defined in the previous patch to
indicate if XRender does GOOD/BEST are true.

This patch also includes some changes to take advantage of the fact that
if there is an integer translation analyze_filter will already have set
the filter to NEAREST.
