So I guess this line will be redundant? Or is it okay to move the new line over
here as id and pointerType are sometimes used together later on.
Also are you sure that in every path that a Touch object is created it has a
pointerType set? Otherwise at this point WebTouchPoint will have
PointerType::Unknown type instead of Touch (or the new pen type).

   point.id = touch->identifier();
   point.screenPosition = touch->screenLocation();
   point.position = convertAbsoluteLocationForLayoutObjectFloat(
       touch->absoluteLocation(), layoutItem);
   point.radiusX = touch->radiusX();
   point.radiusY = touch->radiusY();
   point.rotationAngle = touch->rotationAngle();
   point.force = touch->force();
   point.state = state;
+  point.pointerType = touch->pointerProperties().pointerType;
   return point;
 }
