Again, the inter-frame timer is individually implemented in the GUI
itself meaning that they have to trigger redraw. I'd simply add a
argument "redraw" to Gui::display(). Basically the same as
want_redraw() but in a more direct way.

No, it's rather simple. The invalidated bounds can be altered by the
individual GUI. It can extend or shrink the bounds as it likes. When
the GUI knows about what parts of the window are exposed it can limit
the invalidated bounds to this area. This is already possible.

In the case of a minimized player you can limit the invalidated bounds
to just one pixel or you avoid calling gui->display() which means you
have to advance_movie() manually.
