DEFORM: add support for Regions

Allow more than the default number of concurrent VERTEX and FRAGMENT effects in Effects3D.

New vertex effect 'PINCH'

Complete moving center to 3D.

Unify Effects3D and Matrix3D (still incomplete!)

Encode more info in the EfectNames enum.

Progress with WindManager.

Dynamics: Introduce 2 Modes of operation:

- 'random access' mode, where we are able to call a single Dynamic from multiple thread simultaneously.
- 'sequential' mode, which only permits sequential interpolation from one client.

The second mode has an advantage when one needs to change mDuration: it keeps on interpolating smoothly. In the first mode, this is not possible.

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!
