- *  when the OS is deciding whether to drag your window, but it fires for lots
- *  of other reasons, too, some unrelated to anything you probably care about
- *  _and when the mouse isn't actually at the location it is testing_).
- *  Since this can fire at any time, you should try to keep your callback
- *  efficient, devoid of allocations, etc.
