The only somewhat supported way to do this is documented in Tech Note 276:
"Gimmie Depth Or Gimmie Death (So You Want to be a Monitors Impersonator?)"
which details a new call (SetDepth()) availiable in System 6.0.5.  This
tech note is probably up on Apple.com via anonymous ftp.

Of course this call will only work with 6.0.5 (or later).  Has anyone
else come up with some code which will work on earlier versions? Is the
author of Switcheroo out there?  Are you willing to share?

Thanks--

Tom
