I don't think this is particularly indicative of Harry being a metamorphmagus. It was uncontrolled and subconscious, and neither of Harry's parents were. Considering Lily was muggleborn I think all evidence is against Harry being a metamorphmagus. Given Tonks' discussion with Harry about it and the lack of anything more being brought up about it, I think the books are of the opinion that Harry isn't one. In all honesty, I wouldn't be surprised if JK Rowling hadn't even thought up metamorphmagi by the time she wrote book one.
It seems to be indicated that they can change their appearance to that of any other human within reasonable limitations. They probably can't change their height by too much, and they can probably only add a certain amount of weight. Other than that, I think the books sort of indicate anything goes.
