<pre>WebKit2 View Gestures (Smart Zoom): Can't double-tap zoom-out on the body
https://bugs.webkit.org/show_bug.cgi?id=127602
Reviewed by Anders Carlsson.
* UIProcess/mac/ViewGestureController.h:
* UIProcess/mac/ViewGestureController.mm:
(WebKit::ViewGestureController::ViewGestureController):
(WebKit::ViewGestureController::didCollectGeometryForSmartMagnificationGesture):
Use an explicit boolean instead of the emptiness of the renderRect() to determine
whether or not the user has already smart-zoomed. renderRect() can be 0x0
if our hit-test hits the body element.</pre>
