Re: gnustep-back font display broken on cairo

[Fred Kiefer]

I would not like to revert this change even though I agree with you that pull 
requests this big are bad. The overall changes here are good and in most cases 
we see no issues with them. As for your specific setting, did you try to run 
with the property "GSFontHinting" set to the value 17? This should switch back 
to the old behaviour for font hinting. If this does not help you should try to 
revert part of the changes. This is easier as it seems. Most of the changes in 
this pull request deal with font names and weights. That is irrelevant for the 
font displaying and you may just ignore those changes. Which leaves you with 
less than a handful of interesting changes to look into.

That is currently all I can say as I am away from my computer.
