While it is running, it creates cached bitmaps but they don't get
saved in the image on the disk. The geometry is saved as series of
short-int points. Which can ben fairly big. A .ttc font comes with
Windows for Japanese (which is a substantially big char set) adds only
20MB or such to my image, so liberation-fonts must have really big set
Look at an instance of TTFontDescription (or... if it is using
TTCFontDescription) for it, count the number of entries in glyphs and
glyphsTable, and tell us how many chars there.
