[pitivi] Discoverer: Limit size of video to thumbnail to 720x720.

[Edward Hervey <edwardrv src gnome org>]

commit ab81f4fd774e046d86bec93ec39a665c5973968e
Author: Edward Hervey <bilboed bilboed com>
Date:   Sun May 10 11:55:49 2009 +0200

    Discoverer: Limit size of video to thumbnail to 720x720.
    
    We use videoscale in nearest-neighbour mode (which is faster).
