Pointer Handlers should expose the current pointer type

It's very cool that you can select to which pointer device(s) an handler should respond using the accepted* properties, but I'd still like to reveive the actual values for these properties belonging to the current event. 

If you only want a slightly different reaction based on the pointer type (adjust a margin perhaps, change an icon next to the visualized touch point, or change the placement of something you drag in respect to the point because a finger covers the touch screen, or...) it is beneficial to re-use the same handler instead of defining a whole list of them which share 90% of their content but ony set one different item. 

So, I think these values should be exposed in some way. I guess the best way would be to expose them as as a set of current* properties mirroring the accepted* properties that control what is reacted to.
