Make the effect Center be always 3D.

re-generate noise after passing each Point.

1. Workaround for th issue that my shitty Nexus 4 crashes while compiling the vertext shader (actually the wave function)
2. Improvements to the Dynamics app

minor stuff

Make the WAVE effect 5D (extra parameter 'offset')

swap the 2nd and the 3rd parameters in the WAVE effect and improve comments for the WAVE user API.

Switch off the pre-compulting of sin and cos in CPU as it turns out that those two are single-instruction functions on any modern GPU ( http://www.gamedev.net/topic/322422-number-of-gpu-cycles-for-cos-and-sin-functions/ - link form 2005 ! )

Improve the comment the WAVE effect.

Correct one more issue with computation of WAVE.

Correct one issue with incorrect shadows in WAVE when V.z <0 .
