That will eliminate one resampling, but you still will have the resampling
of the IIgs RGB required to store a line to re-output it at VGA rates.

Since there are so many "VGA" pixel counts per line, it's anyone's
guess how many samples the converter takes.  If it's much larger
than the number of dots the IIgs produces (280/560/640), then the
oversampling may make it a non-issue.

Please do--that will be very interesting.
