Skeleton of the new App: Vertex3D. So far just a copy of Matrix3D.
Rename Effects3D to Matrix3D
Upgrade what used to be the 'Scratchpad' app; step 1: rename.
Further reduce the distortedObject's API - now only 26 methods, 1/4 of the 104 before the reorganization.
Beginnings of support for the 'Save' app.
