If we don't need to support existing use of clientX (for hover) at FB maybe we shouldn't include it on the event objects

[trueadm]

True, but I wasn't 100% sure if it wouldn't be used. I'll leave it in for now, we can take a stab at removing a bunch of these later and using higher level versions possibly.
