Subject: If MaximumTapsRequired is 1, it is not waiting for a multi-tap, so a Tap gesture... 
X-Git-Tag: dali_2.1.10~4^2

If MaximumTapsRequired is 1, it is not waiting for a multi-tap, so a Tap gesture send a single tap.

Even if set to tapGestureDetector.SetMaximumTapsRequired(1);
When user tap multiple times quickly, the tap gesture event now fires only once every maximum Allowed Time (500ms).

If MaximumTapsRequired is 1, user want to receive tap gesture events immediately because we are not waiting for a multi-tap.
