Message:

We want a bad/poor mask distinction in the mask convolution for stacking. Again, otherwise the number of bad pixels just explodes. Since convolving a mask with the PSF-matching kernel is something we want to do in both stack rejection and normal convolution, pulled the code that determines the size of the 'bad' region into a separate function in pmSubtraction.c. Then pmStackReject basically does the same thing that's happening in pmSubtractionConvolve/convolveRegion: go through the image by footprints, convolve the footprint and plug the result back in to the original image. Small API change for pmStackReject. This is very effective in reducing the amount of bad pixels in the stacked image.
