r4133 changed all progress events to regular events the "loaded" field doesn't make sense for a media engine that doesn't keep data buffered, and because we don't have a concept of "loaded" any more.

scheduleProgressEvent() used to call updateFromElement(), which I think updated the controller for a progressively downloaded file. I'm not sure what will do that now.

Updated patch to call renderer->updateFromElement when posting a 'progress' event.
