Tag and push 4.1.1

[tbowers7]

I work with the PypeIt development team, and we are seeing an issue on certain platforms where ginga crashes upon clearing a canvas in advance of displaying images from within PypeIt.

The crash happens with the pip-installed ginga-4.1.0, but not with ginga-4.0.1 or installing ginga directly from the current main branch here on GitHub (listed by pip as 4.1.1.dev18+g4815b44). We conclude that there was some issue introduced in version 4.1.0 that has since been resolved. We request that the current main be tagged and released to resolve this issue when installing the latest version of ginga via pip/PyPI.

There were new features merged since, so looks like it has to be at least a 4.2. What do you think, @ejeschke ?

I have a 4.1.x branch queued up for a 4.1.1 release. I would be comfortable releasing that ASAP. @tbowers7, could you check whether that branch fixes the issue for you?

I had a tentative release date of October for v5.0, but I don't anticipate major changes before then, so it would also be possible to move that up.

@ejeschke, yes, I can confirm that the 4.1.x branch works as expected (no crash), whereas the v4.1.0 tag does crash.

FWIW, here is the traceback for one of the crash modes of v4.1.0, if it will help diagnose any other possible issues:

@tbowers7, ginga v4.1.1 has been released. It's on PyPI and will be out soon on conda-forge.
