Description:
   Draw a browse widget.  Actually, we cannot make a browser that is dynamic
   therefore we really draw an editor widget and we say it is a browser.
   
   This is just like a editor drawing except:
      (1) name is different
      (2) _U._TYPE = "BROWSE"
      (3) set to DOWN 6
      (4) different calls.

Input Parameters:
   <None>

Output Parameters:
   <None>

Author: D. Ross Hunter,  Wm.T.Wood

Date Created: 1992 

Modified on 01/30/97 gfs Added _U._SCROLLBAR-V which defaults to TRUE
