[osg-users] x and y coordinates

[Christian Buchner]

Basic OpenGL utilities libraries like GLUT that provide some mouse events
in the mouseEvent(int button, int state, int x, int y); function, but this
functionality is not native to OpenGL.

Event->x()/y() sounds more like an OSG event handling, and there are plenty
of OSG examples out there that process mouse and keyboards events.
