Basically don't abuse OSG as badly. We need to let it know we've bound a shader program so it doesn't assume the FFP is still used, but it doesn't have a built-in way to apply the uniforms when doing so, so we need to do it manually.
This depends on the difference between FPS which is dynamic and ripples update
frequency which is contant. If FPS > ripples update frequency, some frames do
nothing. If FPS <= ripples update frequency each frame runs shaders once. Update
offset, possitions shader uniforms only when it will be run.
