KuwaharaFilter.osl flipped along UV

[pageau]

In C4D the xxxx filter was flipped along the UVs.

I looks like this is the problem

// Get the base UV coordinates
vector uv = vector(u, -v, 0);

and it should be

// Get the base UV coordinates
vector uv = vector(u, v, 0);

I am not sure if that fixes it for all DCCs or if some need it as -v
