+ * This is a widget specifically for displaying high-resolution digital
+ * camera photos giving speedy feedback (fast load), low memory footprint
+ * and zooming and panning as well as fitting logic. It is entirely focused
+ * on jpeg images, and takes advantage of properties of the jpeg format (via
+ * evas loader features in the jpeg loader).
+ *
+ * Signals that you can add callbacks for are:
+ * @li "clicked" - This is called when a user has clicked the photo without
+ * dragging around.
+ * @li "press" - This is called when a user has pressed down on the photo.
+ * @li "longpressed" - This is called when a user has pressed down on the
+ * photo for a long time without dragging around.
+ * @li "clicked,double" - This is called when a user has double-clicked the
+ * photo.
+ * @li "load" - Photo load begins.
+ * @li "loaded" - This is called when the image file load is complete for the
+ * first view (low resolution blurry version).
+ * @li "load,detail" - Photo detailed data load begins.
+ * @li "loaded,detail" - This is called when the image file load is complete
+ * for the detailed image data (full resolution needed).
+ * @li "zoom,start" - Zoom animation started.
+ * @li "zoom,stop" - Zoom animation stopped.
+ * @li "zoom,change" - Zoom changed when using an auto zoom mode.
+ * @li "scroll" - the content has been scrolled (moved)
+ * @li "scroll,anim,start" - scrolling animation has started
+ * @li "scroll,anim,stop" - scrolling animation has stopped
+ * @li "scroll,drag,start" - dragging the contents around has started
+ * @li "scroll,drag,stop" - dragging the contents around has stopped
+ *
