 That's another point: doing "instant" refresh bypasses the possibility to
 run any PHP hooks and callbacks that may be needed. I know we don't
 currently filter "background-color" for example but a plugin or theme may
 decide to filter it. Currently that's not possible to show in the preview.

 Regarding speed: right, postMessage is faster than "full" refresh of the
 preview, however this has it's drawbacks (no IE < 10 when cross-domain,
 i.e. on most multisite installs current IE won't work). Also speed is
 somewhat relative, it's "nice to have" but shouldn't prevent running hooks
 on the user settings.
