Since nobody seems to know about dpi on Mono, I have changed my
application to specify font sizes in pixels instead of point. That works
well on any platform.

I'm used to px sizes on the web since browsers on some Linux systems
couldn't handle the conversion right in the past and rendered fonts much
too small. And as screen resolutions on the desktop don't seem to change
much (to say 300 dpi) this isn't much of a problem anyway.
