Right, that's what it's meant for. Of course, better would be to
redraw only those parts that have been exposed (does GTK tell the
coordinates). Since we introduced SnappingRanges in the meantime, we
should redesign wants_redraw and replace it by a SnappingRange.

Irrespective of that there should be no problem with intermediate
states because the GUI would just wait otherwise and all ActionScript
is done right before rendering a new frame. Maybe video is different,
but at worst some parts of the player get updated earlier and that
should be barely visible.
