1) MouseTracker - Simulated touchenter/touchleave events now bubble to parent element MouseTrackers
2) MouseTracker - Improved multitouch support in enter/exit event handlers
3) MouseTracker - orphaned tracked touch pointers removed (fix for #539)
4) MouseTracker - removed touchenter/touchleave event support since the events don't exist on any known platform and have been removed from the W3C specification
5) Removed Viewer onContainerPress/onContainerRelease handlers (and the associated 'container-release' event ) that were never fired due to the canvas (child) element capturing the DOM events
6) Added 'canvas-enter', 'canvas-exit', and 'canvas-press' events to Viewer
7) ButtonGroup - removed obsolete MouseTracker event handlers
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
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)
