(* A "GraphicsBase.T" is an abstraction of a window system (e.g. X, Trestle, 
   or NT) and a 3D graphics library (e.g. PEX or OpenGL). 

   I have not yet isolated the window- and graphics-system dependent code;
   this is on my to-do list. Consequently, this interface still needs to be 
   fleshed out. *)
