If your GraphichsContext3D allows a similar drawing performance and capabilities, it might be a better choice. So how would you implement http://www.w3.org/TR/SVG/filters.html#feTurbulenceElement with G3D?

I would find a shader on the web to do it :-)

GLSL, OpenCL and Apple's CoreImage shading language are all just high level language interfaces to the GPU. So I believe what you can do with one you can do with the other. OpenCL may end up having a nicer syntax for some effects, but I think you can ultimately do the same thing with any of them. And since we're not talking about exposing the shader syntax to the author(yet!), I'm not sure it matters.
