* @property {Boolean} [preserveImageSizeOnResize=false]
* Set to true to have the image size preserved when the viewer is resized. This requires autoResize=true (default).
*
* @property {Boolean} [allowZoomToConstraintsOnResize=false]
* Set to true to allow the image to remain zoomed out past the home zoom level during resize.
* If false the image will be zoomed in if necessary such that it touches the edge of the viewer.
* This requires autoResize=true (default).
*
* @property {Number} [pixelsPerWheelLine=40]
* For pixel-resolution scrolling devices, the number of pixels equal to one scroll line.
