Tom Dexter had a patch for this that in particular correctly
handled the case of displaying interlaced content to a display
in an interlaced configuration. It would be good to account
for that mode of use while fixing this. (I can't remember
the details now, but I am pretty sure that what he did
never made it to trunk.)
