I completely agree with Jerome, and would like to add that tests of
the DIB engine would probably be accepted into the tree. Since Max
knows the finer notches of the DIB engine, taking the time to write
some tests would seem to be a good idea - both to speed up the future
migration and to make sure we're not missing any quirks. It may also
help pinpoint certain bugs within the implementation.
