Could you please explain the problem with the font panel? That's a GUI 
class and I don't have any idea what the xlib backendmay do differntly here.

I know that we do the font rendering in pixel sizes, which would be easy 
to change, but is needed because of the third problem in your list. When 
the rest of the drawing is done in pixels than the text also has to be 
done in pixels. If this is really annoying for people we should think 
about scaling all points in the XGViewPointToX like functions using the 
pixel size of the X server. I must admit that I don't like the idea to 
much, as X draws best, when you try to draw directly on pixels, but as 
we are already doing a lot of coordinate conversions things may just not 
get worse. We should give it a try. At least it would solve the oldest 
outstanding GNUstep bug report.
One problem I see with this is that drawing would be done in point size, 
whereas window operations are done in pixel size. How does the art 
backend handle this?
