OK, here's an update. I've made changes that allow GF to
compile on SBCL with cffi-newtypes. But there are some issues:

- the newtypes branch has deviated from the main cffi branch in a couple
  of incompatible ways. The mechanism for defining type translators is
  different (this was the cause of the SBCL compile errors), and there is an
  incompatible change to CFFI:FOREIGN-STRING-TO-LISP.

- there are other problems on LispWorks 5.0 and CLISP that need to be
  worked out yet. I'm pursuing the CLISP issue now and will hopefully figure
  out a patch or something for LW.

So I've created a branch called graphic-forms-newtypes where we can
work with cffi-newtypes for the time being:

svn://common-lisp.net/project/graphic-forms/svn/branches/graphic-forms-newtypes

Some quick testing shows that there are repainting problems that need to be
tackled. So this branch should be considered even more experimental than
the main trunk.
