Thanks. I was wondering if I ought to mention that one.
(since I'm behind the XO port and may be a wee bit biased)

Other than scanning for font files in a background process,

BTW, the size of Tux Paint can be adjusted. The truly fearsome
source of bloat is localized audio descriptions of the stamps.
Starter images are another big source.
