Vibration API: clamp argument

Hi, would it make sense to add the [Clamp] attribute to the argument of the
vibrate method? This would be added in WebIDL.

See the Clamp attribute here:
http://dev.w3.org/2006/webapi/WebIDL/#Clamp

Without it, navigator.vibrate(-1) becomes navigator.vibrate(4294967295).

It seems clamping it to 0 would be a more elegant way of handling this bad
input.

What do you think?

Regards,

Michael
