This is a port of HSC-976 to LSST. The original issue description was:
We should set the polygon bounds (added in
DM-2981 [was HSC-973]) for HSC CCD exposures to cover the non-vignetted regions. This should probably be done in ISR or some other camera-specific location.
Note that, contrary to the description in
DM-2981, this functionality was not included there.
