Clean up and bug fixes in the TouchExplorer.
1. The downTime of the first down event was zero but it should the event time.
2. Hover exit events were not injected while transitioning to delegating
state and when tapping.
3. Differentiation between dragging and delagating state based on
two moving pointer direction and distance is now based only on
the direction. Hence, two pointers moving in the same direction
are dragging, otherwise the event stream is delegated unmodified.
The reason for that is the blind people cannot easily determine
and control the distance between their fingers resulting in
different behavior for gestures which the user thinks are the same
which creates confusion. Also in some cases the delegation and
draggig yield the same result, for example in list view, further
adding to the confusion. This was also causing the status bar to
be opened closed inreliably creating frustration.
4. Refactored the code such that now there is only one method that
injects motion events and all request go through it. Some bugs
were introduced by inconsistent implementation in the different
injection methods.
5. Fixed a couple of event stream inconsistencies reported by the
event consistency verifier.
