Bug 573583. Enable decode-on-draw. r=jrmuizel

Relanding again. I've been unable to understand the regressions and
I can't reproduce them locally anymore. None of the measurements
relavant to this patch change negatively, and we know this is
the direction we want to go. The saner memory behaviour is worth
any small regressions that this might cause.
