f0f6e93915 Adding functionality for https://github.com/openseadragon/openseadragon/issues/127 - option for home button to fill rather than fit.
- Added a option to pass to the OpenSeadragon constructor called homeFillsViewer, which defaults to false. If true, the home button will fill the viewer with the image, centered on the image's center, zoomed to fill the viewer at the image's smallest dimension, and clipped at the image's largest dimension. For example, a very tall, thin image in a 4:3 aspect ratio viewer will zoom so that the width of the image fills the viewer, and most of the height of the image is clipped.

60da75aede Added configuration around the rotate left/right buttons. The default for showRotationControls is false to preserve existing functionality. Also added default tooltip strings for the buttons.
This version runts the tests fine locally using 'npm test'. It looks like the remote build was having a timeout issue which I couldn't reproduce.

Mark Salsbery
0d29c98df2 Enhanced Navigator Resizability (#280, #296)
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.

8e325a3748 Added preventDefaultAction flag to MouseTracker
Added a boolean preventDefaultAction property (default false) to the
event object passed to MouseTracker handler methods. Implemented in the
following MouseTracker subscribers:

* Viewer.keyboardCommandArea.innerTracker.focusHandler:
preventDefaultAction == true prevents scrolling viewer into view
* Viewer.keyboardCommandArea.innerTracker.keyHandler:
preventDefaultAction == true prevents viewer keyboard navigation
* Viewer.innerTracker.clickHandler: preventDefaultAction == true
prevents viewer zoom on click
* Viewer.innerTracker.dragHandler: preventDefaultAction == true prevents
viewer panning with mouse/touch
* Viewer.innerTracker.scrollHandler: preventDefaultAction == true
prevents viewer zooming on mousewheel/pinch
