[AstroPy] Image combine

FYI, I once tested pyCuda
http://mathema.tician.de/software/pycuda for 1D and 2D FFT
computations. I found that the crossover on a multi-core Tyan MB was
~4k N, below that, the (extra) bus transfer time exceeded the FFT speed-up.
But, I would expect the speed advantage for large images to be
significant, particularly FITS cubes where multiple operations are
performed while the data stays in GPU memory. With faster, wider 64
bit bus break-even might be even lower - I should test on my new P6200 MB.
