     Displays a data source in a graphics window and creates a dialog
     to allow navigation of the data display via key strokes.

_U_s_a_g_e:

     tcltkViewer(v, bg = "grey90", region = "red")

_A_r_g_u_m_e_n_t_s:

       v: An object of class 'Viewer'. 

      bg: The colour used for the background of the data overview (see
          Details below). 

  region: The colour used for the viewed region in the data overview
          (see Details below). 

_D_e_t_a_i_l_s:

     The dialog contains key-stroke instructions for navigation, plus
     an overview of the data source being viewed.  This overview
     consists of a rectangle with the approximate dimensions of the
     entire data source and a smaller rectangle (red by default) that
     shows what portion of the data source is currently being viewed in
     the graphics window.

     The dialog must have focus for the key-strokes to have any effect
     on the view in the graphics window.
