/*
sadly there seems to be no way to impose clipping on a child view,
especially a QTMovieView which seems to ignore the current context
completely. Also there is no real way to shape a window; on Aqua a
similar effect to non-rectangular windows is achieved by using a
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.
