drastically reduce the heap usage of FreeType, especially in the case
of memory-mapped files. The idea is to avoid loading and decoding tables
in the heap, and instead access the raw data whenever possible (i.e.
when it doesn't compromise performance).
This had several impacts: first, opening vera.ttf uses a ridiculous amount
of memory (when the FT_Library footprint is accounted for), until you start
loading glyphs. Even then, you'll save at least 20 Kb compared to the non
optimized case. performance of various operations, including open/close
has also been dramatically improved.
More optimisations to come. The auto-hinter eats memory like crazy? This
must be stopped...
