- * many, many files: several memory optimizations were implemented to
- 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
