Distorted Android

2 bugfixes:

- in Dynamics, it has to be t<=0.5 (rather than t<0.5) (see comment in code)
- in EffectQueueVertex, we need to postprocess() the last time, when effect is finished but not removed!

Minor details

Progress with Wind

Tidy up 'Cubes' app

Bugfix

Bugfix (sometimes, when t=0.5 exactly, it wouldn't recompute Noise in case of PATH mode)

re-generate noise after passing each Point.

Flag app finished

Next fixes for issues with 'jumping' path when noise is on. (and a whole lot of commented out debugging)
