[pointerevents] Pull Request: clarification why mouse is always primary

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

== clarification why mouse is always primary ==
This generalises the treatment of mouse inputs to allow for the 
possibility of systems that support more than one simultaneous and 
independent mouse device, while at the same time clarifying that 
currently most (all?) operating systems/user agents don't have a 
concept of multiple mouse pointers. 

It future-proofs the spec while also reflecting reality.

Closes #49
