Reviewed by Eric Carlson.

The source intrinsicSize is used to compute the final video frame size in case constraints are setting only the width or only the height.
Make sure to set the intrisic size whenever the preset is set, which happens when the source gets created, at applying constraints time.
This ensures the intrinsic size is not zero when computing the video size after resizing.
