Please add a detailed note here to clarify that this is a work in progress, to
prevent other teams picking it up in the incomplete state. In particular,
mention that:
- this is used only in Blink event handling
- and for a limited case (to touch-only).

Done.

Let's use the coordinate names as in WebMouseEvent, and quote crbug.com/508283.

Removed completely as your CL makes this unnecessary.
