I'm still opposed to adding an environment variable for something so
simple (an enable/disable flag). It just seems like extra work for no
benefit to me. I'm sure we can all agree that the registry is a
suitable place for the setting.

Isn't the idea that the DIB engine will only be used as needed, and
will be good in all cases where it's used? If that's the case, it's
not too important having on-the-fly per-application enabling/disabling
(whereas WINEDEBUG and WINEDLLOVERRIDES can be VERY useful).
