PR: Add mappings for QMouseEvent methods (#408)

* Might close #394
* Rephrase a comment, as @CAM-Gerlach suggested
* Test the fix for #394
* Format the docstring as suggested by @CAM-Gerlach
* Ensure the created window is of sufficient size to point at
* Don't wait before moving and clicking the mouse.
  `QMainWindow.show()` finishes when the window appears. So, no extra waiting needed.
* Don't close the window at the end
