Initial feedback on the d3d pipeline indicates that we need to improve
the way we handle on-screen rendering.

For application rendering to the screen (without a back-buffer)
100ms update time is too slow.

Also, some apps use BufferedImages as back-buffers. They also
suffer from 100ms delay because we only force onscreen updates
on VI-> screen copes.
