Chrome allows WebTouchPoint to store WebFloatPoint, instead of WebPoint.

This is the first of three patches converting WebTouchPoint to use
WebFloatPoint instead of WebPoint. This introduces some temporary
casts to WebPoint in chromium, which will be removed as soon as
blink has WebTouchPoint storing it's location in a WebFloatPoint.

The second patch (https://codereview.chromium.org/149053002/) 
will be a blink modification to store WebFloatPoint,
and the third patch (https://codereview.chromium.org/148453012/) 
will clean up the chromium side.
