83 sadly there seems to be no way to impose clipping on a child view,
84 especially a QTMovieView which seems to ignore the current context
85 completely. Also there is no real way to shape a window; on Aqua a
86 similar effect to non-rectangular windows is achieved by using a
87 non-opaque window and not painting where one wants the background
88 to shine through.
89
90 With respect to SalObject this leaves us to having an NSClipView
91 containing the child view. Even a QTMovieView respects the boundaries of
92 that, which gives us a clip "region" consisting of one rectangle.
93 This is gives us an 80% solution only, though.
