			<tt>glutPostRedisplay</tt> marks the normal plane of current window as needing to be redisplayed.
			<tt>glutPostWindowRedisplay</tt> works the specified window as needing to be redisplayed. After either
			call, the next iteration through <a href="glutMainLoop.3GLUT.xml"><tt>glutMainLoop</tt></a>, the window's display callback
			will be called to redisplay the window's normal plane. Multiple calls to <tt>glutPostRedisplay</tt> before
			the next display callback opportunity generates only a single redisplay callback.
			<tt>glutPostRedisplay</tt> may be called within a window's display or overlay display callback to re-mark
			that window for redisplay.
		</p><p>
			Logically, normal plane damage notification for a window is treated as a <tt>glutPostRedisplay</tt> on the
			damaged window. Unlike damage reported by the window system, <tt>glutPostRedisplay</tt> will not set to
			true the normal plane's damaged status (returned by <tt>glutLayerGet(GLUT_NORMAL_DAMAGED)</tt>.
		</p><p>
			If the window you want to post a redisplay on is not already current (and you do not require it to be immediately made
			current), using <tt>glutPostWindowRedisplay</tt> is more efficient that calling <a href="glutSetWindow.3GLUT.xml"><tt>glutSetWindow</tt></a> to the desired window and then calling
			<tt>glutPostRedisplay</tt>.
