[ros-users] Camera Sensors in Gazebo and Rviz

So I am going to answer my own question.  In RVIZ, the camera images are
added as 2d images planes to the ogre scene graph of RVIZ.  If you want to
see the other RVIZ renderings, you can lower the alpha value of the image
plane.  This alpha value setting is in the left hand settings panel of RVIZ.

Thank you and sorry for the trouble.  I did not expect to be able to combine
the RVIZ rendering and the image like that so I did not look for the
setting.  Its a great feature though.
