Comment:

 As I understand, the simple kernel convolution is straightforward to
 implement only for data on regularly spaced grids. If so, it is not
 suitable for interp1d and interp2d, which must support data on irregularly
 spaced grids.

 However, we could use a new function for working with regularly spaced
 data. In principle `scipy.ndimage.map_coordinates` does kernel
 convolution, but it is not easy to discover or very convenient to use for
 interpolation (because it is was written for image processing purposes).
