Support --stereo-type option
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
Right now there is a --stereo command line option that turns on stereo rendering. However, it forces the stereo rendering to be the red-blue type (unless the rendering.xml file was edited). There should also be a --stereo-type= flag that allows you to set the type of stereo to one of the entries in the StereoType property of the RenderWindow proxy.
