It sounds like what's needed is an abstraction layer at the platform/graphics level.  Then we could have OpenCL, GLES, GraphicsContext3D or other implementations of the filters.

This could either be by new methods on GraphicsContext, or a new interface entirely.  A new interface would have the advantage of being more modular, so ports could choose a filter backend independently of the choice of GraphicsContext backend.

It might also be possible to refactor the existing FilterEffect hierarchy to have multiple implementations.  That would be a bit tricky, though, since there are some dependencies on ByteArrays, and other CPU-specific details even in the base class which would have to be abstracted away.
