DESCRIPTION

       When  Tk  creates  a  new window it assigns it the default visual characteristics (visual, depth, and colormap) for its screen.	Tk_SetWin-
       dowVisual may be called to change them.	Tk_SetWindowVisual must be called before the window has actually been created in  X  (e.g.  before
       Tk_MapWindow  or  Tk_MakeWindowExist  has  been	invoked for the window).  The safest thing is to call Tk_SetWindowVisual immediately after
       calling Tk_CreateWindow.  If tkwin has already been created before Tk_SetWindowVisual is called then it returns	0  and	doesn't  make  any
       changes;  otherwise it returns 1 to signify that the operation completed successfully.

       Note:   Tk_SetWindowVisual  should  not be called if you just want to change a window's colormap without changing its visual or depth; call
       Tk_SetWindowColormap instead.
