Click Trampolines - support to trampoline pointer events into 'click' events

- This is needed to support Fullscreen on IE11 because IE only trusts 'click' events for this operation; click trampolines as a general solution, although they are only required in some "special" cases.
Pointer - minor documentation update for click trampolines
Pointe - removed extra whitespace
