//    Removed initialization of exceptions and added general initialization.
//
//    Brad Whitlock, Mon Nov 27 16:10:21 PST 2000
//    I added a flag preventing the argument list from being messed with during
//    general initialization.
//
//    Jeremy Meredith, Fri May 11 13:52:51 PDT 2001
//    Added initialization of PlotPluginManager.
//
//    Jeremy Meredith, Thu Jul 26 03:34:42 PDT 2001

//
//    Brad Whitlock, Mon Oct 22 18:25:42 PST 2001
//    Changed the exception handling keywords to macros.
//
//    Jeremy Meredith, Tue Jan 14 17:12:34 PST 2003
//    Added setColorSpec(ManyColor) so that it will try to get a 24-bit
//    visual for the GUI windows, even if 8-bit is the default.
//
//    Hank Childs, Tue Jun  1 14:07:05 PDT 2004
//    Added call to finalize.
