Setting projector pose vs. enclosing link pose?

edit

In gazebo 1.9.2 I see behavior where setting the pose of a projector produces glitchy results (see left of image below), whereas setting the pose of the link enclosing the projector looks as expected on the right:

I observed a similar glitch using projectors launched from ROS Hydro urdf/xacro files ( http://answers.ros.org/question/11872... ), I need to experiment to see if I can get it working there by only manipulating the link pose and avoid using the projector pose.
