1. In the magnifier we are caching the touch events until we figure
out whether the user is triple tapping to enable magnification.
If the user is not trying to engage magnification we deliver the
stashed events. However, these events are stale and the subsequent
transformations such as the touch explorer get confused when trying
to detect a tap since the delay is longer than the tap slop.
This change compensates for the time the events were cached
before sending them to the next transformation in the chain.
