Convert Rubik app to stretchless API.
Fixes for the merge.
Move the 'pre-multiply mesh before applying any effects' thing from [(Xsize of texture, Ysize of texture) x Mesh's zFactor] to Effects.setStretch(sx,sy,sz)
Simplify the way applications can get notifications when an effect finishes.
Now, instead of the 'DistortedEffects.(de)registerForNotifications()' 2 APIs, we call a single 'Effect.notifyWhenFinished()'.
Correct the Legal notice.
Rename all the classes that are not exported to application to 'Internal'
minor.
Turn the Rubik app into a MemoryTest.
Another bugfix: if we keep changing the cube size and rotating sides at the same time, then it could happen that ability to rotate was permanently withdrawn.
Fixes for memory leak problems uncovered by the 'Rubik' app. (mainly: new method DistortedNode.markForDeletion)
Port changes from the 'distorted-cube' target.
Rubik App: minor
Rubk App: changes in the UI
Rubk App: improve 4 buttons in the top.
RubikCube: make the post-rotation effect 'nice'.
Many things.
1) make the Dynamic.setDuration() able to be called AFTER the Dynamic has already been run. (and rename it to 'makeRunNowFor()' )2) remove the automatic removal of zero Effects from EffectQueues.3) adjust several Apps to cope with 2)4) add post-rotation to Rubik (still not finished)
RubikApp: properly compute cameraDistance and FOV.
RubikApp: minor
RubikApp: make the rotations smooth.
RubikApp: simplifications.
Improve the architecture of the Rubik App.
Improve the architecture of the Rubik App: new RubikCube class.
Improve the Rubik App - rotation works now.
Improve the Rubik App - beginnings of rotation.
Improve the Rubik App.

Improvements for the 'Rubik' app.
1) new 'Rubik' app (skeleton)2) MeshCubes: add support for custom texture mappings on each side (Rubik needs that!)
