Window::invalidate(bool) should fire an event.

Issue #712 resolved

Currently there is no way to be notified when a window is invalidated. It would be good to add an event for this.

Reproducibility: N/A

Additional information: Always be aware of potential performance impacts. It's probably worth measuring before and after speeds here.

    Event is actually fired by the Window::invalidate_impl function.

    Timed this before and after - the version firing the event is 0.56% slower. Given that invalidation should be a infrequent event relative to all the other stuff going on, this essentially equates to an insignificant increase (IMO).
