We can easily make it work for psfs and images with different pixel scales.

  1. deconvolve image by pixel
  2. deconvolve psf by its different pixel
  3. deconvolve image by pixel-deconvolved psf
  4. do metacal shears
  5. reconvolve image by original pixel and chosen pre-pixel psf

we should probably add a check that the psf pixel scale is not larger than the image pixel scale by more than a tiny amount (which can happen due to noise in the wcs)

this can wait until after 2.0 comes out.
