And to the question why people still use Windows try setting up your X environment to properly support MathML with Firefox.
Truly, using new fonts within X is a black art still reminiscent of dark and medieval times when we did not know better. I thought we would have progressed that stage by now.
From a user perspective Windows definitely wins hands down in this, drag a file to a Fonts folder, done.
No, X wants us to use crazy incantations of mkfontdir, mkfontscale, fc-cache, ttmkfdir, xset with various fp options and hope xlsfonts shows the font you are after.
Users do NOT want to be bothered with foundries, weights, encoding types, and what not. They just want to add a font, select it in their favourite application and go: "owww, pretty!"
Is that, anno 2004, too much to ask?
