+   sadly there seems to be no way to impose clipping on a child view,

+   non-opaque window and not painting where one wants the background
+   to shine through.
+
+   With respect to SalObject this leaves us to having an NSClipView
+   containing the child view. Even a QTMovieView respects the boundaries of
+   that, which gives us a clip "region" consisting of one rectangle.
+   This is gives us an 80% solution only, though.
