depending on the implementation, a zero-sized QPolygonF may not
have any underlying buffer allocated and may return a null pointer when
queried for its "data()"
this null pointer is returned to Python as a "None" which breaks code
not expecting it.

On Windows, pyreadline is emitting a deprecation warning we can ignore.
Furthermore, test_svg was using NamedTemporaryFile in a manner that was
causing permission denied errors, so this commit switches to the use of
pytest friendly temporary files
This file contains two tests, one of which has been skipped forever,
and the second (test_pg_exit) has been a flakey test that does not test
in general, testing a use-case we likely do not see any more. So
therefore I am removing this test from the library.
While this fix prevents an assertion error, the assertion error was
being suppressed; and was only noticeable via pytest -s where the error
was printed to console. Future work should be done to minimize the use
of bare exceptions so these tests do not fail silently
Remove if __name__ == "__main__" bits, replace some == None to is None
checks
Cleanup variety of static code checker issue
Removed missing imports, restructured some logic to make a little
cleaner, fixed a function in test_dockarea, unfortunately broke the test
so now I tell pytest to expect the Exception.
the test_signalproxy.py had a fixture for the QApplication instance,
only problem is at the end of each use of the fixture, it would mark
the application instance for deletion, which is most definitely not what
we want
To reduce complexity, and make it easier to add more images and tests,
the images in the `test-data` repository should be merged with the main
repository. Furthermore, we can remove a lot of the subprocess work in
the image_testing.py file, as we no longer need to have it interact with
git.
The images are not the same. Images were regenerated with Qt6, and now
have proper big and little endian handling thanks to @pijyoi
Second commit is a slightly modified variant of
2e135ab282d6007b34a3854921be54d0e9efb241 authored by @pijyoi
it is to convert qimages to RGBA8888 for testing. Image
files were regenerated images for the big/little handling
Fixed issue with bogus test from test_NonUniformImage and generated a
new image
