Distorted Android

Properly detect which drivers are slow with compilation of TF programs.

Fix for an invalid enum.

New debug to print a whole component of a mesh.

Create the bandaged 3x3 icon: something works, the shape is drawn, but it's entirely black. Investigate.

Further progress with Bandaged 3x3.
This requires a new API in DistortedNode to change the Mesh there.

Very important bugfix in the Library: MatrixEffectQuaternion cannot share the tmp static buffers!

new API to enable/disable face culling

Preparation for drawing only the FRONT side of the cubit walls.

Extra API for QuatHelper.

Minor.
