Detailed Description

Abstract interface for objects that can consume Glut interaction events (click, drag, hover, and keyboard). Method names and their signatures come from Glut's API e.g. the drag method is called "motion" after Glut's glutMotionFunc() function.

Returning "true" indicates that the function has consumed the event and other listeners won't receive it.
