"Abstract renderer" takes octave object tree as input and has abstract methods 
for rendering like "DrawAxes", "DrawGrid", "DrawCurve", "DrawSurface", etc. 
The "Real renderer" is a derived class that implements all those abstract 
methods and therefore provides some output (it could be OpenGL as well as 
anything else).

I mean it's very slow because Linux graphic driver for SiS cards is not very 
good. I don't see any way to overcome it.
