Btw, a relatively isolated place in the code to deploy and test
weak references would be "active" and "topmost" mouse entities
in the mouse_button_state class.
That class stores the character currently under the mouse,
which is looked for on mouse move.
If you do not move your mouse, but the character disappears,
we want that pointer to become NULL.
