 // A platform independent implementation of BrowserWindow for Panels.  This
 // class would get the first crack at all the BrowserWindow calls for Panels and
 // do one or more of the following:
 // - Do nothing.  The function is not relevant to Panels.
 // - Throw an exceptions.  The function shouldn't be called for Panels.
 // - Do Panel specific platform independent processing and then invoke the
 //   function on the platform specific BrowserWindow member.  For example,
 //   Panel size is restricted to certain limits.
 // - Invoke an appropriate PanelManager function to do stuff that might affect
 //   other Panels.  For example deleting a panel would rearrange other panels.
