DESCRIPTION
       A main window is a special kind of toplevel window used as the outermost window in an application.

       If interp is associated with a Tk application then Tk_MainWindow returns the application's main window. If there is no Tk application asso-
       ciated with interp then Tk_MainWindow returns NULL and leaves an error message in interp->result.

       Tk_GetNumMainWindows returns a count of the number of main windows currently open in the process.
