c5099d30b1 [renderer] Fix access to freed memory loading fonts 
QFS_LoadFile closes its file argument (this is a design error resulting
from changing QFS_LoadFile to take a file instead of a path and not
completing the update), resulting in the call to Qfilesize accessing
freed memory.

935e883d8d [renderer] Switch to using HarfBuzz for glyph positioning 
This means that QF should support more exotic fonts without any issue
(once the rest of the text handling system is up to snuff) as HarfBuzz
does all the hard work of handling OpenType, Graphite, etc text shaping,
including kerning (when enabled).

Also, font loading now loads all the glyphs into the atlas (preload is
gone).

4d5b38f0c9 [renderer] Star work on adding FreeType support 
Right now, this just initializes the library and loads a font into
memory, preloading a given set of characters (specified by unicode
values).
