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...
rename all the 'grid' variables to 'mesh'.
Rename Grid to Mesh
Fix a lot of Lint warnings in the apps.
Change of names.
Hide the 'depth' of a DistortedTexture inside the library, so users do not get exposed to this weirdness.
Complete the split DistortedObject -> (DistortedTexture,DistortedEffectQueue)
Beginnings of split of DistortedObject into two separate classes: DistortedEffectQueues and DistortedTexture.
Still does not compile, but pushing already.
Rename various classes; fix a bug in Around the World.
More fixes for the recent API change.
Major change in API: separate the GRID from DistortedObject; completely remove classes derived from DistortedObject.
Make the effect Center be always 3D.
Unify Effects3D and Matrix3D (still incomplete!)
Tidy up 'Matrix3D'
Skeleton of the new App: Vertex3D. So far just a copy of Matrix3D.
Rename Effects3D to Matrix3D
