Sugar's fonts

I agree that the DejaVu fonts are far from optimal. There are some
instructive comments on the wiki about seemingly mundane things like
the shape of the 4, etc.

While we certainly will have a mechanism for varying the basic system
font and size, for the most the activities where the majority of
reading is expected to take place have mechanisms for scaling already
(Read and Write). The interface in the browser is not yet exposed and
Etoys is a place where we expect children to spend time reading and
writing as well.

That said, I'm not sure that we'll find one set of metrics for all
activities and all children from running field tests. But we could be
better informed about some of the default settings.
