It seems like CodecImages are sometimes being used for drawing after
they have been marked as unused for the MCVD shared image pool.  It
is likely that this happens when the renderer is torn down before
receiving returns from viz (e.g., renderer crash).

This CL causes CodecImage to handle these cases gracefully, rather
than crash.
