Distorted Android

Add a new API DistortedEffects.exists(long id)

Make per-component centers optional, controlled by API MeshBase.setUseCenters()

Bugfixes as a result of the Samsung Galaxy J4+ investigation:

1) By default, switch off transform feedback in the main program.
Create a new API 'needTransformFeedback()' to call if someone still needs TF in the main program.
2) lower the default max number of vertex effects to 30....

Progress with Megaminx.

Remove UBO from the fragment shader and come back to the default of only 5 concurrent fragment effects. All because UBOs in fragment shader crash on Adreno 510 and Adreno 506.

Minor.

Properly initialize DynamicQuat.

Remove all the calls to DistortedLibrary.setMax() (except for app 'Check', which explictly checks this API)

Introduce another Uniform Block Object. Now we can have much more vertex and fragment effects - up their default number to 100.

Plug two more memory leaks. It should be fine now.
