Hi Ben,

can you please run this and send the output back. I expect we also have a API 
change between 10.4.11 and 10.5.x:

bash$ grep -re "gluTessCallback" \
/System/Library/Frameworks/OpenGL.framework/Versions/Current/Headers/glu.h

and this one please

bash$ grep -re "glGetIntegerv" \
/System/Library/Frameworks/OpenGL.framework/Versions/Current/Headers/gl.h

That is not quite correct. It does work very well - what does not work is 
resizing the figure window and therefore the callback if the figure window 
should be resized. I spent some time some while ago to find out what is going 
wrong, but I've not been successful - maybe somebody else on a Mac can have a 
look at this (but I still expect it has nothing to do with the sources Octave - 
I expect the problem is in the sources of fltk).

Meanwhile you can change the function "default_size" in 
src/DLD-functions/fltk_backend.cc to this:

  void default_size (int& x, int& y, int& w, int& h)
  {
    x = 0;
    y = 0;
    w = 560;
    h = 440;
  }

then your drawings should be good (mouse resizing window still without 
functionality). Am I right or wrong?

Best regards,
