/**
* Report user touch activity when touch events occur
*
* User activity is used to determine when controls should show/hide. It's
* relatively simple when it comes to mouse events, because any mouse event
* should show the controls. So we capture mouse events that bubble up to the
* player and report activity when that happens.
*
* With touch events it isn't as easy. We can't rely on touch events at the
* player level, because a tap (touchstart + touchend) on the video itself on
* mobile devices is meant to turn controls off (and on). User activity is
* checked asynchronously, so what could happen is a tap event on the video
* turns the controls off, then the touchend event bubbles up to the player,
* which if it reported user activity, would turn the controls right back on.
* (We also don't want to completely block touch events from bubbling up)
*
* Also a touchmove, touch+hold, and anything other than a tap is not supposed
* to turn the controls back on on a mobile device.
*
* Here we're setting the default component behavior to report user activity
* whenever touch events happen, and this can be turned off by components that
* want touch events to act differently.
