   settings such as track selections, custom tracks, and track hubs. Any changes
   you make in this new session will, however, affect the user's settings.  E.g.,
   if you add a track in this new window, and come back to the genome browser
-  later, this track will appear there. This setting is useful if a website

-  changes that they made still to be there.

   (At the moment,
   there is no visual indicator in such a Genome Browser window that changes are not saved, 
   but we could add one 
   in the future, please contact us if you think this could be useful for you.) 
   This variable is probably 
   useful for most websites using our tool hgRenderTracks to show only the
   Browser's main image from a Javascript-driven website.
