Re: gnustep-opal small bug (fwd)

[Fred Kiefer]

The NSFont code in Opal never did match the one in gui. These are to 
alternative implementations, or rather the Opal one is a prove of 
concept. If you want to use Opal together with gui you need to switch 
off OpalText (for which there is a make switch) or remove the text 
support out of gui.

The correct solution here would be to rewrite the OPFreeTypeFont class 
to be a subclass of GSFontInfo and to change NSFont to better support 
font descriptors. This isn't too much work there just is nobody with 
enough time.
