Message:

psImageShiftKernel is redundant now, with psImageShift calling psImageInterpolate.

-/** Shift image by an arbitrary number of pixels (dx,dy) in either direction.
- *
- *  If the shift values are fractional, the output pixel values should
- *  interpolate between the input pixel values. The output image has the same
- *  dimensions as the input image. Pixels which fall off the edge of the
- *  output image are lost. Newly exposed pixels are set to the value given by
- *  exposed. This function must be defined for the following types: psU8,
- *  psU16, psS8, psS16, psF32, psF64.
- *
- *  This implementation uses a NxN kernel generated based on the interpolation method
- *  the image is first shifted by a fractional amount with the kernel, then
- *  shifted in place by an integer amount.
- *
- *  XXX the integer shift portion is not implemented
- *  XXX the exposed pixels are not properly replaced
- *  XXX the algorithm can properly handle a mask, but the API does not include
- *  it (and it is not implemented)
- *
- *  @return psImage*     the shifted image result.
