Bug 1507615 - part1 : don't activate document if the 'pointdown' is originated from touch event r=smaug

Browse Source 
For touch events, we use 'touchend' to activate document, because 'touchstart' can be the start of either draging
or touch. As 'pointdown' is a precedent event of the 'touchstart', we should not activate document if the source of
event is from touch event.
