Separated event-model/device specific event handling code from
event-model/device agnostic event handling code.
Use enter/leave events instead of over/out events.
Updated unit tests for above changes.
Added unit tests for mouse gestures.
Updated changelog for breaking changes and deprecations.
Removed zoom on click for touch.
Added an isPrimary flag to gesture points.
Fixed documentation error and updated documentation and comments.
Implemented the stopHandler for mouse events.
All event handler signatures changed to 'fn(event)'
eventSource property added to the event object passed
Redundant event source properties removed ('button' and 'viewer'
Documentation updated in MouseTracker
changelog.txt updated
Documentation fixes
isTouchEvent property removed from eventData where not used
'eventOrTouchPoint' var name used and 'originalEvent' var name restored
to 'event'
Misc name changes, indentation/whitespace fixes.
Still TODO: Fix documentation, evaluate presence of key handler in a
mouse tracker, evaluate whether isTouchEvent flag should be in all
eventData objects or not.
Implemented "Expose original event in handlers" (#23) for MouseTracker
Added OpenSeadragon.getElementOffset() method. Element-relative mouse
coordinates should be correct even if the element and/or page is
scrolled (#131)
canvas pans when tap on touch screen
reason:
onTouchStart calls onMouseDown which registers 'mousemove' event handler.
when I tap on touch screen, even though browser did not dispatch 'touchmove' event, it dispatched 'mousemove' event.
therefore, the 'mousemove' handler pans canvas.
fix:
stop onTouchStart handler registering 'mousemove' handler as onMouseMove will be properly triggered by onTouchMove

strange to list no copyright date newer than the original CodePlex

Dragging the canvas did not work on Android devices as the === check for
lastTouch and the current event was always evaluating to false.
Presumably Safari on iOS re-uses the same Touch object for touchmove
events with the same finger, whereas Chrome/Firefox on Android creates
new Touch objects for each event (so the === evaluates false). The code
now compares Touch.identifier to ensure the new touch event is from the
same finger as the initiating touchstart.
