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 associated with interp then
Tk_MainWindow returns NULL and leaves an error message in
interpreter interp's result.
Tk_GetNumMainWindows returns a count of the number of
main windows currently open in the current thread.
