And in SVN trunk (and, when released, 0.21), there's support for
complete control over which rendering method is used for playback of
various types/resolutions of recordings.  For now, though, the
0.20-fixes-compatible approach that Chad suggested is recommended.  I'm
just mentioning that it will be officially supported in the future.
