This is needed to get aura-based platforms to honor vsync being disabled,
otherwise the scheduler ticks at the vsync rate instead of ticking when the
swap-ack arrives.

I could move this to a separate patch if needed.

+1 for a separate patch so we can more easily tell the rest of this is a no-op.

   settings.partial_swap_enabled =
       !command_line->HasSwitch(cc::switches::kUIDisablePartialSwap);
