I would first add bicubic support in a separate patch.

Why limit that to 4 channels? Just pass in the number of channels.

The GPU compositor uses BSpline not Mitchell, so if we decide to use it, we need to update the GPU compositor as well.

This introduces more interpolation differences between CPU and GPU, but they are not really related to the patch, so can be handled separatly.
