Water surface object.

This object displays a water surface. The surface extends from (-size_x/2,-size_y/2,-max_amp) to (size_x/2, size_y/2, max_amp) Texture coordinates are generated also. (default: (0.0,0.0)-(1.0,1.0))

The maximum amplitude defaults to 1.0, the default resolution is 8 subdivisions per side, which means 128 triangles.
