* CornerMenu is a menu is intended to be placed in one of the four corners of a pane.
* It will show the provided menu items in a 90 degree arc with the origin in the corner.
* It is possible to, and per default will, animate the menu items in and out of view.
* The showing and hiding of the menu items can be done automatically based on the mouse pointer location.
*
* CornerMenu requires a Pane to attach itself to.
*
* CornerMenu uses CircularPane and this will leak through in the API.
* For example: it is possible to customize the animation, and required interface to implement is the one from CircularPane.
