Distorted Android

Make the 'Component Associations' UBO (on most devices) twice smaller -
use the 'packed' layout and 'ivec2' in place of 'ivec4'.

This forces us to dynamically probe the 'Stride' - number of 4-byte entities that the UBO's 'ivec4' takes - and correct the already-constructed UniformBlockAssociation objects in case this turns out to be different than the expected 2, i.e. tightly-packed....

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.

Plug a major memory leak.
Still one more leak remains - a similar UniformBuffer has to be markedForDeletion in the EffectQueues.

Convert the Integer part (i.e. effect names and the two associations) of vertex and fragment shaders to Uniform Buffer Objects.
Next: convert the last part, i.e. the float effect parameters.

Cleanups

Fixes for the Rex Cube (mostly works now)

Bugfix: fix a long-standing bug where switching on normal vector drawing would interfere with transparency.

Bugfix: always normalize the normal vector after modifying it, otherwise the next effect might not work correctly (Distort!)

Bugfix: we initially need to set the maxTextureSize to MAX_INT, because otherwise early (i.e. before a call to onSurfaceCreated) calls to setTexture() will fail.

Put new things to the StackFrame.

Put new things to the StackFrame.

Minor.

Fix the fact that the static DistortedEffects.mAllQueues was global, shared between all Activities.
Completely replace this mechanism with a non-static list of links from a VertexEffect to all VertexEffectQueues this effect is a member of.

Fix the fact that we would keep adding new InternalBuffers to the 'Done' list - split 'invalidate()' and 'recreate()' to two separate actions!

Start creating the Tutorial Activity.

More support for using the library from more than one activity. Should be working now!
