Realtime preview of the effects of project settings for resolution and pixel aspect ratio

Description
Ideally, when the user changes the resolution or pixel/display aspect ratio, we should automatically update the previewer widget to reflect the changes, so that the connection to pixel aspect ratio is made clear.
If the user clicks OK, then the settings are indeed applied.
If the users clicks cancel, then the previewer resets to the previous values.
