We generate pointer events from touch events on Firefox. Width and height come from touch radius, which is fetched from OS. Checked [touch event spec](https://w3c.github.io/touch-events/#touch-interface), it says "The radius of the ellipse which most closely circumscribes the touching area along the axis indicated by rotationAngle, in CSS pixels of the same scale as screenX; 0 if no value is known. The value must not be negative.". Current behavior seems reasonable for me.

Wondering if this causes some problems or blocks some features? Not opposed to change it, just want to know more.
