Distorted Android

Major refactoring: convert the Matrix Effects to be independent of the resolution of the surface we render to.

Re-write the first 15 apps to work with this.

Minor.

Minor.

Fix PlainMonaLisa's Activity lifecycle (it wouldn't work after a POWER button press, i.e. after a brief time in the background - surfaceCreated is not called in this case)

Convert (almost) all remaining Apps to the new API which avoids memory leaks with Surfaces.

Remaining problematic Apps: 15. FBO 16. Star Wars (both leak Tree FBOs) 22. SurfaceView (does not work at all after going to background)

Major:

1) in the Library, fix the fact that some applications (those that were creating their DistortedSurface objects outside of onSurfaceCreated or onSurfaceChanged) would not render after the activity went to background (press POWER to see that).
2) in the Apps, call the new 'Distorted.onPause()' API to fix the above problem...

Multiblur: add FPS

Separate the Postprocessing Effects to their own DistortedEffectsPostprocess queue.
This partly breaks Multiblur (to be debugged)

Remove debug prints.
