Nevermind.  I was being bitten by the "special case" of
dstStride == srcStride in which the whole image is copied in
a single memcpy.  I need the stride-by-stride copy of, e.g.,
my_memcpy_pic, that several folks have implemented in their
various filters.

Problem solved for the moment.  Sorry for the interruption.
At some point I hope to have a patch ready for review by you
folks.
