[Pharo-project] FreeType

Hi all. Using the latest FreeType (admittedly on a 3.9 image, though probably generally applicable) we are noticing quite a lot of cache thrash, meaning that the low-level glyph rendering is happening quite often. Really noticeable on slow machines (our deployment target has 800MHz processors). Was wondering if it might me a good idea to move the cached form rendering into a plugin (lots of bit manipulation in Squeak code loops)? We've stabilised thing for the moment by hanging onto the LogicalFonts used and modifying the real font lookup to reuse existing matches and switching to CRT mode (3 times quicker). First use of glyphs at varying subpixel positions miss the cache though. Regards, Gary.
