This would also help with fonts that have incomplete hints, like the URW 
fonts shipping with Ghostscript. They have blue zones and hints, just... 
not everywhere they need to be. Some figures in Nimbus Sans and the rest 
of the family miss hints at the top of glyphs, which currently messes 
with hinting.
