   MODULE  : PCO_VIEW_CORE

   PURPOSE : This Modul contains the core viewer class
             with basic functions and handlers for several PCO control 
             messages.
             It is intended to be specialized and extended, e.g. in 
             GUI-server-applications.
             Some member functions are totally virtual without any 
             standard body and have to be provided by the child class !
