Marks the specified window as needing to be redisplayed.
glutPostWindowRedisplay marks the specified window as needing to be redisplayed. The next iteration through glutMainLoop, the window's display callback will be called to redisplay the window's normal plane.
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 glutPostWindowRedisplay is more efficient than calling glutSetWindow to the desired window and then calling glutPostRedisplay.
