Distorted Android

Progress with thr Glow effect - moving glow app looks ok now.

More progress with a more generic 'preprocess' stage of Postprocessing Effects.

Progress with a more generic 'preprocess' stage of Postprocessing Effects.

1. Hide internalQuality inside Postprocess effects.
2. First step to turn markStencilAndDepth into a more generic Postprocessing 'preprocess'.

Hide the FBO_QUEUE thing inside the library. The queue is running internally now, without public setAsOutputFBO() thing (simplifies writing postprocess effects)

Partially 'fix' Glow effect for the case when FBO_QUEUE_SIZE > 1 (come back to pre-FBO_QUEUE_SIZE level of functionality).
Still, Glow needs to actually get implemented correctly.

Simplify Main OIT shader.

a mix of two changes:

1) remove the DistortedInputSurface interface (now every Surface is Input)
2) make the OIT SSBO self-adjustable in size

Make the OIT SSBO size independent of screen size.

Remove the redundant DistortedNode.onPause()
