Message:

Configurable display double-buffering

On by default (since turning off creates flicker in the absence of
front-to-back rendering). This is the quick and dirty way: display
server renders locally to a bitmap (using mem GC) and renders the
bitmap when ready.

The more sophisticated way would be to implement buffering in the
display device. That would require, however, enhancing the protocols
to communicate frame boundaries.
