<pre>[EFL][WK2] Add a logic for checking multi touch in GestureRecognizer::noGesture
https://bugs.webkit.org/show_bug.cgi?id=127675
Patch by Sanghyup Lee <sh53.lee@samsung.com> on 2014-02-02
Reviewed by Gyuyoung Kim.
When processing TouchStart event in GestureRecognizer::noGesture(), we should
check the number of touch points to distinguish if the gesture is single tap
or pinch zoom. Current logic only considers the event as single tap.
* UIProcess/API/efl/GestureRecognizer.cpp:
(WebKit::GestureRecognizer::noGesture):</pre>
