        a wxWindow based value, in which case it might determine the widget, the
        display the window is on, or something similar. The window given should be as

        Width in pixels of a rectangle centered on a drag point

        Non-zero if the meanings of the left and right mouse buttons are swapped; zero
        otherwise.

        @a win is a pointer to the window for which the metric is requested.
        Specifying the @a win parameter is encouraged, because some metrics on some
        ports are not supported without one,
        or they might be capable of reporting better values if given one. If a window
        does not make sense for a metric,
        one should still be given, as for example it might determine which displays
        cursor width is requested with
        wxSYS_CURSOR_X.
