Distorted Android

new VertexEffectRotate

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.

Do not allow more than 15 characters in the NAME.

Move to AndroidX, target API level 29.

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.

Progress with of Pyraminx.
Bugfix for joining a single Mesh!

Improve setTextureMap.

Make MeshBase.setTextureMap() work.

Minor.
Looks like MeshBase.join() actually works.

Fix MeshBase.join()
Only upload Mesh Buffers to GPU when we actually use them.

New MeshJoined.
Test app says it's not working - bug in MeshBase.join().

Further corrections.

Port Listener to the new setStretch-less API.

Convert Projection to not use the depreciated MeshBase.setStretch() API.

Correct the Rubik app for the recent changes to the library's Node.

Size of the FBO internal to Nodes is now NO MORE taken from the Mesh's stretch values.
Instead, the size is copied from child's FBO size (if there is one) or if the child is a leaf with texture in it (which is sizeless) then we get the default 100x100 ( which means we probably have to explicitly call Node.resizeFBO() )

Minor.
