Maybe it makes sense to mention the abbreviations once in the tracing
output.

I wouldn't have thought that...

Dave, how is that handled in Adobe's Type1->CFF converter?  Do you get
similar rendering differences?  Does the old Adobe Type1 engine hint
on the fly, or does it perform two passes, where the first pass builds
a hintmap so that hints are `optimized' for the whole glyph, and the
second pass does the actual hinting?
