// 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.
