+//
+// So, for example, if you were to have a CreateTabsControl/wxNotebook
+// and change pages, even if you called HIViewSetVisible/SetControlVisibility
+// directly the movie will still continue playing on top of everything else
+// if you went to a different tab.
+//
+// Note that another issue, and why we call MCSetControllerPort instead
+// of SetMovieGWorld directly, is that in addition to rendering on
+// top of everything else the last created controller steals mouse and
+// other input from everything else in the window, including other
+// controllers. Setting the port of it releases this behaviour.
