   1 The design of most of this code is such that we extend the GLX structures
   2 with a void * named apple.

   4 The GLX functions that need to do Apple-specific things are passed
   5 &s->apple in order to initialize the private structures.

   7 Thus when updating, just run a diff against glxext.c or glxcmds.c, and
   8 manually merge from there as needed.
