I can't find "sans" or "Sans" in o_text.c 
grep for "Sans" over the whole pcjc2 dir, returns the localename  
"Sanscrit" ;-)

Maybe you meant some other branch?

Isn't it possible to do all the glyph rendering in advance for a couple 
of zoom stages? Or even pre-render the whole schematic. I suspect my 3D-
CAD application, varicad, plays these tricks to achieve amazingly fast 
zoom for thousands of polygons even on a moderate desktop.
