no that was for scaling the font so the height was consistent. It seems to 
have been enhanced when split out into osd.cpp, etc.
however the fundamental asymetric h/v scaling didnt work properly in ttfont 
class so it picked the best it had available, and most fonts only gave 1 
choice, i.e. no narrow and wide alternatives (not that you should need them 
with ttfs). I suspect if we look, the default font has at least the narrow 
alternative charsets. not that I know much about freetype fonts so I am 
guessing a bit.
