Re: [Touch events] createTouchList should probably take a sequence, not an IDL array

According to http://www.w3.org/TR/WebIDL/#idl-operations, I believe the
correct WebIDL would be:
TouchList createTouchList (Touch ...touches);

I believe the iOS and upstream WebKit implementaions implement only this
form today.  I believe I can add the array form to upstream WebKit, but I
have no influence over the iOS implementation.

Matt, how should we proceed?  I don't consider this API to be very
important, so I don't think this should be a huge deal (eg. identifiedTouch
is also something that not all implementations today support).  What's the
impact if we change the spec to match the original implementations, and
move the array-form constructor to v2?
