/* The only non-trivial bit of this is the *Tess* functions.  Here we
   need to wrap the callbacks up in a thunk to switch calling
   conventions, so we use our own tesselator type to store the
   application's callbacks.  wine_gluTessCallback always sets the
   *_DATA type of callback so that we have access to the polygon_data
   (which is in fact just wine_tess_t), in the thunk itself we can
   check whether we should call the _DATA or non _DATA type. */
