Message:

Reworking psImageInterpolate so that kernels are pre-calculated. Renamed a few things in the process: psImageInterpolateOptions --> psImageInterpolation (shorter), PS_INTERPOLATE_BICUBE --> PS_INTERPOLATE_BIQUADRATIC (accurate). I've moved all the interpolation kernels into 1D so that I can pre-calculate them with a reasonable amount of memory. This might be a mistake for the BIQUADRATIC kernel (doesn't have an obvious 1D kernel function), so I might revert just that one soon. Haven't checked if the speed is faster yet, but I checked something in that broke the build, so I need to check this in. Tests pass.
