Note:

1. The VISIBL Argument will be set to .TRUE. if the specified Viewport is visible and .FALSE. otherwise. The Viewport Priority may still inhibit the display of the Viewport if it is negative. Thus a Viewport returning VISIBL as .TRUE. and PRIOR as negative will not be visible.
2. The PRIOR Argument is optional and, if present, is set to the current Priority of the specified Viewport. If this is negative it will inhibit the display of the Viewport.
