I created the fonts automatically, from a sample rendered with FreeType,
using area each glyph uses. In this case, the $r has a very light blue
pixel at the topRight. I can modify the script to ignore pixels that are
too light when setting the bounds for the glyph, but I can not guarantee
perfect results unless glyphs are tweaked by hand.
