Depends on the pen. In the low end, you flip the pen around to bring the
virtual eraser on the tablet, so there are 4 states:

        hovering with pen
        pressing with pen
        hovering with eraser
        pressing with eraser

the more advanced ones have some buttons, and also advanced tablets can 
recognize
different pens.

Mouse Wheel.

Like I mentioned, this is irrelevant for OpenGL where we handle all events
ourselves.
