If we average this (is that fair?) it would come out to:

   2100 "width" * 22 "height" * 4 "depth" * 5 "fonts" * 5 "sizes" * 32 

=> 147,840,000

Uhm, no, not really. It's a new feature not a fix. As such, it should be 
treated with some caution. I'm not saying that it can't be included but 
there are some aspects about it that make me feel very uneasy (for 
example the whole kadoodle in Grafport - I'm virtually certain that 
there will be situations where this is wrong).

As a matter of fact I'd probably vote for leaving StrikeFont completely 
alone and introduce a new font subclass for these guys. It makes clear 
where the assumptions are and the extension points for fonts are by now 
defined well-enough that these fonts could be one loadable option.

It makes more sense to me if your fonts are one of the loadable options 
from Squeakmap. Then people can decide whether they want one, the other, 
or both.
