Use the auto play property of movies that are not started via
the 'page open' action. That's the case for Rendition-based videos
from PDF documents for example.
Hide the video player initially until the user has clicked on
the annotation area. This ensures that an available 'first-frame' image
is always visible. Also change the appearance of the mouse cursor when
the annotation area is entered.

- add a seek slider to the control bar, that "becomes" a button that popups it when there is too few space for it
- more robust even filter on the phonon video widget
- "eat" the tooltip events, so we don't have tooltips coming from eg the page view
