I do not know anything about fonts
can you explain the cache mechanism for the font rendering?
briefly?

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.
