   PAPCO Draw-window - Basic PAPCO functionality
*******************************************************************************

   This window is the graphics output window of PAPCO. It is automatically
   created the first time you press the Draw Button in the PAPCO main window.

   The last created Draw window is always the current draw window. All
   old draw windows remain on  screen but are no longer active.
   The Draw New Button in the PAPCO main window is used to open a new
   Draw Window for the next graphics output. This then becomes the active
   Draw Window.
   
   All mouse actions set in the PAPCO main window take place when you click
   in this window.

   Selecting Landscape or Portrait graphics in the PAPCO main window now
   also affects the shape of the graphics draw window. When this option is 
   changed in the PAPCO in the PAPCO main window it will only take effect once
   the next new Draw Window is created.

   The filename displayed at the bottom is the current product file name
   used to save the product.


   WARNING:  Do not destroy any old or current draw window using your Window
   ========  managers own "quit" function as this confuses the IDL xmanager.
             ALWAYS destroy old windows using the "Delete old draw Windows"
             or "Close all draw windows" button of the active Draw Window.

   All Draw Windows are automatically destroyed when the PAPCO main Window is 
   exited.
