<tt>glutMotionFunc</tt> and <tt>glutPassiveMotionFunc</tt> set the motion and passive motion
callback respectively for the current window. The motion callback for a window is called when the mouse moves within
the window while one or more mouse buttons are pressed. The passive motion callback for a window is called when the
mouse moves within the window while no mouse buttons are pressed.
</p><p>
The <i><tt>x</tt></i> and <i><tt>y</tt></i> callback parameters indicate the mouse location in window
relative coordinates.
</p><p>
Passing <tt>NULL</tt> to <tt>glutMotionFunc</tt> or <tt>glutPassiveMotionFunc</tt>
disables the generation of the mouse or passive motion callback respectively.
