Class Mouse

src/main/java/fieldbox/boxes/Mouse.java:18–214

Entry-point from GLFW based Window.Event into Field. Boxes can add to properties "onMouseDown", "onMouseMove", "onMouseEnter" and "onMouseExit" to listen to these events. Optionally these can return Draggers that will continue to be notified until corresponding mouse up events

 * corresponding mouse up events.
