Distorted Android

Minor

Improvements for the new Border effect. Now works, but covers the object - to be corrected.

New postprocess effect 'Border' (not working yet) and adding it to the testing app 'Triblur'.

Mesh creation: finished.

Move destroying most of statics from onDestroy() earlier, to onPause().

Reason: doing this in onDestroy() is too late, because when we have two activities, and switch between them, first the ending's Activity onPause() is called, then the starting Activity's onResume, then it's onSurfaceCreated(), then we insert all the effects, and only then the ending Activity onDestroy() gets fired off - and this might destroy the already enabled effects, like for example the Programs of the Postprocessing effects.

Move QuatHelpeer to distorted-library

Add debugging option to DistortedEffects.

On second thought, come back to Vector. The problem: before we had the potentially blocking function 'effectFinished' inside our synchronized block.

Improve EffectMessageSender: ArrayList with explicit locking in place of a Vector.

1) add missing call to BlockController.onPause() / onResume() to the Tutorial activity
2) rearrange BlockController's error reporting to make the case where the MessageSender thread has died separate
3) in such case, resurrect the thread
4) simplify and harden the EffectMessageSender

More debugs to the EffectMessageSender.

Firebase shows that we have a problem when an app is rapidly restarted, i.e. when is it paused and resumes within tens of milliseconds. Then sometimes the EffectMessageSender thread dies.

Attempt to limit this by synchronizing the whole 'start' and 'stop' methods, although I suspect this will still happen because the very methods are probably in such case called in the wrong order.

Some more debugs for the case when the UI is blocked.

Minor.

Convert the Ivy corner cubit to the new, 'universal' cubit creation method.

This forces deep changes to 'createRoundSolid' and the underlying 'MeshPolygon' class to make them support arbitrary Polygon 'centers of face convexity'.

Reason: the faces of this cubit are concave and such default 'center of face convexity' (which by default used to be (0,0)) turned to lie outside the face - which produces strange visual artifacts.

Copy constructors for the Statics.

Dynamics: minor.

Dynamics: consolidation of code.

Dynamics: introduce two speed modes - smooth and segment_constant.
Prepare the third mode - globally_constant.

Bump version to 1.8.0

2 Skewb Ultimate cubits.

RubikControl: fixes; progress.

Make Dynamic's resetToBegin() done on the next frame.
This is necessary if we want to reset many Dynamics at one go and have all of them start synchronized.
Otherwise it can happen that when we reset, we do it when some objects which the Dynamics belong to are already rendered and others are not, and then some of the Dynamics will be delayed by one frame which is visible already.

Progress with RubikControl - sub-stages 1 and 2 of the 'whole' stage finished.

Actually reset Node's mLastTime back to 0 each time we attach it somewhere.
