Henrik:

OK, but Squeak still uses 12, 15, 18, 24 in the font menu, and requires another set of sizes to set the proper font size in a TextMorph as I pointed out.

I don't care what sizes are used, but they should be uniformly used in Squeak and should have some rationale behind the uniform values used.
