Distorted Android

Add the first two VERTEX 'pseudo-matrix' effects: VERTEX_MOVE & VERTEX_QUATERNION i.e. implementations of those two MATRIX effects in VERTEX queue.

The point(s):

1) preparation for the upcoming MeshBase.preApply(VertexEffect effect) API that's going to supersede the current much more limited MeshBase.apply(MatrixEffect effect)...

Do not crash if we failed to compile some programs.

Lower requirements - now only OpenGL ES 3.0 is required; if running on such platform, OIT part of the API ( which is the only one which actually requires 3.1) is switched off.

Progress implementing RubikCube.retObjectString()

Bugfixes in MeshBase:

1) improper buffer was being invalidated after apply and setTextureMap (TFO rather than VBO!)
2) setTextureMap would only work if all components were being set

More support for the 3x3x3 Solver: more of the actual 3x3x3 solver mechanism.

Speedup: only allocate one postprocessing buffer set of the quality we need, not all in one go.

1. library: new API DistortedNode.setProjection()
2. cube: adjustments for Pyraminx.

Fix the memory test - we need to run one thing on the Graphics thread!

Fixes for the Projection matrix, FOV.

There was a confusion between the Projection of the Node onto the Screen, and the Projection of the Cubits on the Node.
