Returns whether the window is part of the current active toplevel.
(That is, the toplevel window receiving keystrokes.)
The return value is %TRUE if the window is active toplevel
itself, but also if it is, say, a #GtkPlug embedded in the active toplevel.
You might use this function if you wanted to draw a widget
differently in an active window from a widget in an inactive window.
