New 'PostprocessTree' app (unfinished)
New 'Glow' app.
Progress with support for Effect classes.
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...
improve Postprocessing; new icon; minor things.
New 'Blur' App. Actual BLUR effect, of course, does not work.
