More support for using the library from more than one activity
We need to pause an Activity in the following way:
1) Activity.onPause()2) View.onPause()3) Library.onPause()
otherwise sometimes there are artifacts when pausing!
Correct the Legal notice.
Rename all the classes that are not exported to application to 'Internal'
Massive: make the coordinate system agree with that of OpenGL (i.e. invert the Y axis).
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...
Slight improvement for the Mirror app.
First attempt at the 'Mirror' app.
