*WIP* Inline type hints

[clemens-fricke]

!!! Currently no type hints !!!

I have started with the example overall similar to tataratat/gustaf#197 to enable type hint tracing also in the examples.
Example tracing with run_all_examples is not possible :(

Also, I wanted to enable us to run the examples in CI/CD to also check them.

Overview

Similar to #381 but not in stub-files but with inline type hinting.

Using https://github.com/dropbox/pyannotate to trace tests to automatically detect the types enables us to add type hints quicker.

Addressed issues

• Type hints are available
• Autocomplete in IDE is better
• During further development adding type hints is easier than using stub-files
• Secondary benefit, check which functions are called during tests and examples

Checklists

• Documentations are up-to-date.
• Added example(s)
• Added test(s)

Dependencies

• Setting setting offscreen default & enable running of example on headless server gustaf#197
  -> Due to using the gustaf setting DEFAULT_OFFSCREEN

I have now tried to add the inline annotations traced from just the tests (using pytest-annotate pytest plugin). This is not as trivial as I had hoped. Basically everything exploded and after fixing some format issues, I have a lot of circular dependency errors. I think it might be good if we look into this during the upcoming HackDayz.

Can you post some circular dependency errors?
