External viewer
---------------

  ArtStudio allows you to show all graphics by external viewers.
  To activate these external "viewers" you have to choose the
  respectively check button ("ON" you will see) and it has to enter
  a path for the respectively viewer. By this way it is possible
  to add new graphic boards into ArtStudio or to show pictures faster
  and in more high-graded quality.

  You have to use the external programs only when the respectively switch
  and the main switch are activated. When one of both isn't activ it will
  be used the internal viewer.

  The main switch turns off all external viewers and only the internal viewer
  will be used.
  
  There is also an external UNIVERSAL VIEWER, which is valid for all graphic
  formats. You have the following possiblyties:
  OFF: The universal viewer will not use.

  On : If you don`t have declared an external viewer, the univeral viewer will
        be started.


  All: Artstudio uses the universal viewer in every case, it doesn`t matter
       if you have chosen an external viewer or not for a specified graphicformat.
