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.
New navigator options:
* @property {Boolean} [showNavigator=false]
* Set to true to make the navigator minimap appear.
*
* @property {Boolean} [navigatorId=navigator-GENERATED DATE]
* The ID of a div to hold the navigator minimap.
* If an ID is specified, the navigatorPosition, navigatorSizeRatio,
navigatorMaintainSizeRatio, and navigatorTop|Left|Height|Width options
will be ignored.
* If an ID is not specified, a div element will be generated and
placed on top of the main image.
*
* @property {String} [navigatorPosition='TOP_RIGHT']
* Valid values are 'TOP_LEFT', 'TOP_RIGHT', 'BOTTOM_LEFT',
'BOTTOM_RIGHT', or 'ABSOLUTE'.<br>
* If 'ABSOLUTE' is specified, then navigatorTop|Left|Height|Width
determines the size and position of the navigator minimap in the viewer,
and navigatorSizeRatio and navigatorMaintainSizeRatio are ignored.<br>
* For 'TOP_LEFT', 'TOP_RIGHT', 'BOTTOM_LEFT', and 'BOTTOM_RIGHT',
the navigatorSizeRatio or navigatorHeight|Width values determine the
size of the navigator minimap.
*
* @property {Number} [navigatorSizeRatio=0.2]
* Ratio of navigator size to viewer size. Ignored if
navigatorHeight|Width are specified.
*
* @property {Boolean} [navigatorMaintainSizeRatio=false]
* If true, the navigator minimap is resized (using
navigatorSizeRatio) when the viewer size changes.
*
* @property {Number|String} [navigatorTop=null]
* Specifies the location of the navigator minimap (see
navigatorPosition).
*
* @property {Number|String} [navigatorLeft=null]
* Specifies the location of the navigator minimap (see
navigatorPosition).
*
* @property {Number|String} [navigatorHeight=null]
* Specifies the size of the navigator minimap (see
navigatorPosition).
* If specified, navigatorSizeRatio and navigatorMaintainSizeRatio
are ignored.
*
* @property {Number|String} [navigatorWidth=null]
* Specifies the size of the navigator minimap (see
navigatorPosition).
* If specified, navigatorSizeRatio and navigatorMaintainSizeRatio
are ignored.
Fixes#280 and #296
Updated documentation doclet.
Enclosed detection code in a function.
Eliminated the Drawer USE_CANVAS global and replaced it with a
Drawer.useCanvas instance variable.
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)
Prior to IE 10, XmlHttpRequest cannot be used for requests to a
different origin even when the target URL's CORS headers would allow
access (see http://caniuse.com/#feat=cors).
This is easy to miss in testing if you use a single origin during
testing but have a CDN or domain-sharding for production and will break
the error handler function passed to makeAjaxRequest() if that code
assumes it can access properties on the request object.
This adds a more informative pointer to Microsoft's documentation when a
security exception is raised.
So far only 90 degree rotation is supported.
Only the image is currently being rotated.
Overlays, debugger, and the navigator still need to be updated to support rotation.
* Use CSS display tables for vertical centering (tested back to IE8)
* Use the DOM instead of string concatenation
* Remove redundant styles ($.makeNeutralElement sets the same values
for margin, padding & border)
* Return the outer wrapper element to ease DOM addition & removal
Setting onreadystatechange can avoid the possibility of it somehow being
called twice but there's no point in nulling the request right before we
let the GC collect it.
* Since async is always true – and browsers are starting to deprecate
synchronous XHR – we were able to prune considerable amount of code
* Add an error callback to match the existing success callback
Previously `request.onreadystatechange` was assigned an empty function
on success but null on failures, which breaks in IE (see
http://jsbin.com/ezozax/6/).
This patch simply mimics the success behaviour in the cleanup function
Closes#143
This previously wasn't in scope outside of the main OpenSeadragon
closure. Now it's exposed with an underscore prefix to encourage people
not to think of it as a public interface.
Mostly unused function arguments but there were also a fair number
of legacy names which are now no longer used.
One question which comes up – mostly in tilesource.js – is whether
there is any value in leaving unused variables for functions which
are intended to be overridden anyway. I'm inclined to say that the
docs + tests need to be sufficient as there's no enforcement that
whatever is in the base implementation will actually be followed by
any of the real functions.
This simplifies setElementOpacity by removing support for the
obsolete, IE-only element.filters property. Also removes a variable
that previously leaked into the global scope.
Very old versions of Firefox - e.g. Firefox 7 - have
window.requestAnimationFrame but not cancelAnimationFrame. This is a
very old release so the easiest fix is simply to check for both of the
functions which we intend to call and fall back on traditional behaviour
if both aren't present.

strange to list no copyright date newer than the original CodePlex

Ideally we'd keep the MIT-licensed helper code in a separate file,
but it proved difficult to extricate from the rest of openseadragon.js.
Also remove comment about plagiarism. It's not plagiarism if it's
attributed and properly licensed.
