Now guys this is something that didn't come up till now...
I installed a set of Unicode TT fonts (liberation-fonts-0.2) in the latest OLPC eToys image  which are about 1 MB and when i saved the image it grew more than 100 MB! How does Squeak load TT fonts? Does it convert them to bitmap fonts before using them? Such a huge amount of space only for fonts is unacceptable for OLPC which has only 1 GB of space...
