commit 7054bb1da4f473062947eba07f81da0b9d0bdffc
Author: Leszek Koltunski <leszek@koltunski.pl>

    Fixes for some stuff discovered while making the Distort effect fully 3D:
    
    - make MeshSphere's normal lengths be 1 (used to be 0.5)
    - make the Effect3D app display precise values of the Center and Region vars.
