Send original event.

It works only for the wheel listener, but not for pinch/move - I was trying to do that not once.
The impetus and touch-pinch don't expose event afaik, so it either needs to be fake or lobby PRs somehow.

This sends the original event of the wheel listener and can be used to detect whether Ctlr key is down when scrolling. At the moment, event is undefined for all events.

This event property is inconsistent for pinch/move, needs to be added for them too.

[kabudahab]

Inconsistent event property is better than undefined. I am happy with how it works now, so I will close.

Just for the reference #17, #18.
I suppose it may be updated from impetus/touch-pinch to something new.
