buggy coloring with the pre_output_filter when expansion is enabled
· tfmdata for different expansion values is split over different objects
· in ``initializeexpansion()``, chr.expansion_factor is set, and only
those characters that have it are affected
· in constructors.scale: chr.expansion_factor = ve*1000 if commented out
makes the bug vanish
