NO, this is not how the system works. the mp_image is associated with
the link between two filters and must never be used in another
context, even if the same underlying buffer is used.

This limitation applies not only to the current architecture (which
sucks), but to any properly-designed architecture as well. However
it's not a limitation at all since two distinct mp_images could share
the same allocation space for the actual pixel data.
