This module contains deprecated things that are removed from the interface.
They are implemented in Python again, together with a deprecation warning.
Functions that are to be called for
PySide6.<module> must be named
fix_for_<module> .
Note that this fixing code is run after all initializations, but before the
import is finished. But that is no problem since the module is passed in.
PYSIDE-1735: This is also used now for missing other functions (overwriting __or__
in Qt.(Keyboard)Modifier).
