get_screen
Description:
Returns the screen for the event.
The screen is typically the screen for `event->any.window`, but for events such as mouse events, it is the screen where the pointer was when the event occurs - that is, the screen which has the root window to which `event->motion.x_root` and `event->motion.y_root` are relative.
