Do you see any way I could do something to ease the pain a bit? One
way might be to try to figure out the prefered font resolution and
put it into the query for the fonts, similar to what you proposed
to do manually with

That wouldn't be a big deal once one knows which is the correct
font resolution for the system. Currently the library tries to
figure out the screen resolution (in lib/flresources.c around
line 1155). Now I could use that for a guess for the appropriate
font resolution. "Interesting" are corner cases when the screen
resolution is near to the middle between 75 and 100 dpi - which
font resolution do I prefer then?

All comments (or better ideas) will be appreciated;-)

                           Best regards, Jens
