Hello,

I plan on doing some demonstrations of ROS using screen captures of rviz 
while the navigation stack is operating.  It would be great to have a 
"radius" or "line thickness" option for the Path display type to make 
the paths easier to see.  If there is already a way to do this, please 
forgive my inability to find it...

Thanks!
