Opal backend (was: GNUstep-corebase to be released next week)

[Ivan Vučica]

Indeed, replacing Cairo as the default (and documenting that Opal should be 
installed before -back for best results) is probably the best way to go for the 
future. Something like this would be required to properly integrate CA, too; 
otherwise, -lockFocus would have to be used and any painting done in the 
current CG context would be applied before or after painting done with 
-lockFocus (which is probably incorrect).

Expanding use of Opal will be a good way to uncover any lingering bugs. A few 
of them are currently listed (and #ifdef'd) inside quartzcore's code, and I'll 
make a list at some point documenting them.
