[Andrea Azzarone]

Fix redrawing of preview cover art.

== Problem ==
Redrawing update for previews cover art. See: http://www.youtube.com/watch?v=LJjPP0lqouA

== Fix ==
Use IsFullRedraw.

Note that there is no need to call QueueDraw when key_nav_focus_change is emitted/received. Nux will do it for you.
