Ultimately, the solution appears to be to return to the 0.21 release
(not -fixes)  build (dated 16 Mar 2008 on the Snider Pad).  This
version of the OSX frontend still allows 1% overscan to remove
borders/noise without a performance penalty, either with OSX 10.4 or
10.5.

If anyone is able to use display scaling on their mac with a version
of 0.21-fixes >= 18547, would you mind letting me know which one?
