avoid dropping our shm-based surface on configure-event
Here is an easy one.
The memfd_create() was getting called not because the committed buffer had not

animation widget resizing. We unconditionally dropped the surfaces when we
could reuse the existing ones if sizing did not actually change.</pre>
