If I offset CRPIX by inserting a shift at the beginning of the GRID to IWC mapping, the resulting WCS cannot be written in FITS-WCS format. David Berry has a fix in AST.
This will require a new unit test in astshim and enables an improvement in ast: the shift can be added after GRID instead of between PIXEL0 and GRID (breaking the desired rule that PIXEL0 to GRID is always a shift of +1).
