Patch to make art backend compile with freetype >=2.1.8

[Guido Schimmels]

gnustep-back-0.9.4 art backend doesn't compile against freetype >=2.1.8.
As I didn't want to downgrade I tried to adapt it to the latest freetype API.
I stopped working on it as soon as it compiled in the night at 4, so it's 
probably buggy.
So far it seem okay. No crashes at least. All my fonts get listed. But changing 
the font
prefs in GNUMail.app has no effect. It will just keep on using helvetica 
bitmaps.
I've only tried GNUstep shortly 2 years ago. And now wanted to have another 
look.
So I don't really know what I'm doing nor how GNUstep with the arts-backend is 
supposed to look like.
But it runs and I can play with the environment.
Probably you have been hacking on that on CVS already and my efforts are 
redundant.
But I'm inpatient. 
If you want something to get done, do it yourself :)

Cheers,
Guido
