						The new special callback function.

			<tt>glutSpecialUpFunc</tt> sets the special keyboard up (key release) callback for the current window. The
			special keyboard up callback is triggered when keyboard function or directional keys are released. The
			<i><tt>key</tt></i> callback parameter is a <tt>GLUT_KEY_*</tt> constant for the special key
			pressed. The <i><tt>x</tt></i> and <i><tt>y</tt></i> callback parameters indicate the mouse in window
			relative coordinates when the key was pressed. When a new window is created, no special up callback is initially
			registered and special key releases in the window are ignored. Passing <tt>NULL</tt> to
			<tt>glutSpecialUpFunc</tt> disables the generation of special up callbacks.
		</p><p>
			During a special up callback, <a href="glutGetModifiers.3GLUT.xml"><tt>glutGetModifiers</tt></a> may be called to determine the
			state of modifier keys when the key release generating the callback occurred.
		</p><p>
			To avoid the reporting of key release/press pairs due to auto repeat, use <a href="glutIgnoreKeyRepeat.3GLUT.xml"><tt>glutIgnoreKeyRepeat</tt></a> to ignore auto repeated keystrokes.
		</p><p>
			An implementation should do its best to provide ways to generate all the <tt>GLUT_KEY_</tt>* special keys.
			The available <tt>GLUT_KEY_*</tt> values are:
