Having said all that, FreeType is a must. The font quality is awesome.

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.
