- Damn thing breaks HARD with non-bitmap fonts, something wonky af with the
  glyph offsets, will have to investigate further.
- Obviously this doesn't work well with proportional fonts, those would need a
  different format where each glyph is a separate graphic with its own offsets
  and stuff.
- Doesn't handle unicode blocks beyond the basic multilingual plane, might
  actually be an issue with freetype itself, or the fonts I use, though I CAN
  see that the glyphs are there if I use a character map program.
- Vertical shift has to be specified manually for some fonts that have some
  sort of built-in offset, I have yet to figure a way to automate this.
