Of failing relativity and singularities!

Concept4b : Pushing and Popping Matrices
========================================

Idea:
=====
So that previous translations do not have an
effect on the position of the next object 
drawn, OpenGl provides to functions glPushMatrix()
and glPopMatrix(). 

Experiment
==========
Try the same experiment as before, notice the
difference, the cube always gets drawn relative
to the orign now!.
