Changeset 9843 for trunk/psModules/src/objects/pmSourcePhotometry.h

Message:

I added code to pmSourcePhotometryAper to shift the source so the
centroid fractional-pixel position matches the centroid of the growth
curve reference object. I make a temporary copy of the object pixels,
then use bilinear interpolation to shift the pixels by the desired
about. Bilinear interpolation is probably too coarse for this step: i
still see a few tenths of a mag error for a 2pixel radius aperture.
note that I added a temporary verion of psImageShift because the
existing code has an error (it seems to be confused about the 0.5
pixel center, or is inconsistent wrt psImageInterpolate).
