[GEM-dev] newWave as a mesh generator

[cyrille henry]

hello,

Curent CVS version of newWave is a primitive that range from -1 to (grid-1 / grid).
here is a diff that fix this small bug.

with this fix, newWave is really draw from -1 to 1, and then it can be used as a generic mesh, specially when working with vertex shader.

so, i think a mesh generator is not needed.
