You want cuis smalltalk. It's a heavily-simplified smalltalk (like pharo, it was also forked from squeak), with a redesigned morphic system - which is ENTIRELY vector graphics based (plus a few other niceties).

Yes, even the fonts themselves are vector graphics. You can use a fancy cursive font, rotate a text window, and then zoom it in or out - with total clarity.

In Settings Browser, check "Set canvas scale factor automatically"

i ran into this problem too. i was able to make it mostly work by changing the font size.
