The approach of using a "CUDABitmap / CUDAMesh" data type to allow the
pipeline to work normally is a clever one, albeit with a significant
downside: it requires the user to explicitly create a "CUDA-aware"
pipeline.  Each of the three alternative approaches has its
pros-and-cons.  Let's ensure that we have some significant examples to
benchmark before making recommendations.  At a minimum we need to see
some mesh computations, both embarassingly-parallel and not.

Cheers,
