			<tt>glutSpaceballRotateFunc</tt> sets the Spaceball rotate callback for the current window. The Spaceball
			rotate callback for a window is called when the window has Spaceball input focus (normally, when the mouse is in the
			window) and the user generates Spaceball rotations. The <i><tt>x</tt></i>, <tt>y</tt>, and <tt>z</tt> callback parameters indicate the
			rotation along the X, Y, and Z axes. The callback parameters are normalized to be within the range of -1800 to 1800
			inclusive.
		</p><p>
			Registering a Spaceball rotate callback when a Spaceball device is not available is ineffectual and not an error. In
			this case, no Spaceball rotate callbacks will be generated.
		</p><p>
			Passing <tt>NULL</tt> to <tt>glutSpaceballRotateFunc</tt> disables the generation of Spaceball
			rotate callbacks. When a new window is created, no Spaceball rotate callback is initially registered.
