With the Xv video rendering mechanism, graphics are drawn onto the
unscaled video, then passed to the video card for scaling. This is why
the OSD looks terrible when you're watching SDTV on a 1080p screen.
However, as you can see, we actually seem to scale the OSD before
drawing, so there's probably something missing for the message dialog
(because the dev who created it probably only tested with the modern
video renderers). So, until someone finds and fixes that bug...
