Ok, this is interesting. I can now run Font2DTest, and you know what? It
looks just fine. At least with plain fonts:


There seems to be a problem with bold fonts though:


I think I hit this with my example, since Swing uses lots of bold fonts
by default, and somehow my FontManager and/or FontConfiguration has
chosen a font that is very bad. Vera Bold looks much better. This
problem with bold fonts is also visible with the OpenJDK X11 pipeline:


So I think it's not my fault.

Also, I think that I did something wrong with my first experiments and
only used one font file, which didn't contain the bold versions, so the
pipeline probably rendered a plain font with bold configuration or
something like this. Is this plausible?

For now I think I have to fix my FontConfiguration and FontManager stuff
(I moved the font code from the GraphicsEnvironment to FontManager
subclasses), so that the correct fonts are chosen, and hope that it
works better then.

Cheers, Roman
