Dispatch function for KernelNgbOp2d (see Global functions for KernelNgbOp2d).

Dispatch is based on the categories defined in NgbT.

Parameters:
dstPtr  Output image: IS = dstSize, IBS = 0
srcPtr  Input image: IS = dstSize+2*(ngbSize/2), IBS = ngbSize/2, srcPtr is at (IX0,IY0)
kernel  Input image, IS = kernelSize, IBS = 0
