Distorted Android

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.
