[pointerevents] Pull Request: Fix the touch-action processing model for zoom scenarios

RByers has just submitted a new pull request for 
https://github.com/w3c/pointerevents:

== Fix the touch-action processing model for zoom scenarios ==
It's incorrect to consider the touch-action values only up to the 
nearest
ancestor that supports ANY default touch behavior.  Eg. in Edge you 
can
disable double-tap to zoom across an entire page (including any 
iframes
or other scrolling elements) by applying 'touch-action: manipulation' 
to
the html element.  See http://jsbin.com/tipure/ and 
http://jsbin.com/jucuna.
This is issue #19.

This change also moves the core processing model details up to
above the specific value definitions to make it easier to follow
without getting lost in all the value-specific notes.
