I added the real space image wrapping but have punted on the k-space stuff. I will submit that in another PR, but it will take longer.
The accuracy loss was not wrapping but due to the WCS bug.
Also as a quick comment. The test suite didn't catch the imul etc. bugs, either in galsim or jax-galsim. It may be that we never got the tests to run all the way to the right spot, but definitely something we should think about for future PRs.
When I enabled the upstream galsim tests for shears, I noticed an orders of magnitude loss in accuracy for rendering images in the test. This PR fixes that.
