* Fourth, in case of a terrible fluke causing this to appear valid erroneously, we verify that each pointer leads into the next.
* And if someone builds their game so the first pointer is absolutely valid length data and the next font is valid glyph data-
* screw it, call Jacky720 when someone constructs that and you want to mod it.
