I couldn't care less for the font currently used by gschem. It is just 
plain ugly when zoomed in. If it were replaced by a real font, the only 
important property is a compatible font metrics.

A glyph like "a" is reused many times on a view with lots of text. So it 
has to be rendered only once and can be copied for the rest of the 
instances. I'd expect glyph caching to help in this situation. If the 
current view contains only little text, speed is no issue in the first 
place.
