commit 1efc38dc3c33fef57b759002db3965ed07a28cb0
Author: Andreas Huber <andih@google.com>
Date:   Thu Nov 19 14:36:14 2009 -0800

    Sending the SEEK-COMPLETE notification temporarily broke seeking backwards in time behaviour. This is now fixed.

    Also, get rid of the semi-random delay after posting buffers to surface flinger in favour of delaying the buffer release until the next frame is displayed.
