Re: ISSUE-111: Add z attribute to mouse events?

I'm fully satisfied with this decision.

I also believe that clientZ deserves a fully thought-out approach.
There's no need to include it in current DOM3 Events.

I've opened a new thread on this list exploring a new event proposal,
based on postMessage, ArrayBuffer, and InkML, where Z-data may be exposed.

However, if we're going to move the eventing world to 3 dimensions, then I could see other applications where you might want a whole new set of client coordinates (e.g., input like Xbox Kinect where the units of mm aren't appropriate).

However, I think the entire concept of 3 dimensional coordinate systems on the web needs to be thought through end to end when taken outside the scope of pen/ink. That kind of work would be appropriate for a future spec--not DOM3 Events.

Future specifications may be able to  better consider such a definition should a need arise. Let us know if there's any concerns with this decision.
