+ * @param mainAction
+ * A JavaScript object literal describing the notification button's
+ * action. If present, it must have the following properties:
+ * - label (string): the button's label.
+ * - accessKey (string): the button's accessKey.
+ * - callback (function): a callback to be invoked when the button is

+ * An optional JavaScript array describing the notification's alternate
+ * actions. The array should contain objects with the same properties
+ * as mainAction. These are used to populate the notification button's
+ * dropdown menu.
+ * @param options
+ * An options JavaScript object holding additional properties for the
+ * notification. The following properties are currently supported:
+ * persistence: An integer. The notification will not automatically
+ * dismiss for this many page loads.
+ * timeout: A time in milliseconds. The notification will not
+ * automatically dismiss before this time.
+ * persistWhileVisible:
+ * A boolean. If true, a visible notification will always
+ * persist across location changes.
+ * dismissed: Whether the notification should be added as a dismissed
+ * notification. Dismissed notifications can be activated
+ * by clicking on their anchorElement.
+ * eventCallback:
+ * Callback to be invoked when the notification changes
+ * state. The callback's first argument is a string
+ * identifying the state change:
+ * "dismissed": notification has been dismissed by the
+ * user (e.g. by clicking away or switching
+ * tabs)
+ * "removed": notification has been removed (due to
+ * location change or user action)
+ * "showing": notification is about to be shown
+ * (this can be fired multiple times as
+ * notifications are dismissed and re-shown)
+ * "shown": notification has been shown (this can be fired
+ * multiple times as notifications are dismissed
+ * and re-shown)
+ * "swapping": the docshell of the browser that created
+ * the notification is about to be swapped to
+ * another browser. A second parameter contains
+ * the browser that is receiving the docshell,
+ * so that the event callback can transfer stuff
+ * specific to this notification.
+ * If the callback returns true, the notification
+ * will be moved to the new browser.
+ * If the callback isn't implemented, returns false,
+ * or doesn't return any value, the notification
+ * will be removed.
+ * neverShow: Indicate that no popup should be shown for this
+ * notification. Useful for just showing the anchor icon.
+ * removeOnDismissal:
+ * Notifications with this parameter set to true will be
+ * removed when they would have otherwise been dismissed
+ * (i.e. any time the popup is closed due to user
+ * interaction).
+ * checkbox: An object that allows you to add a checkbox and
+ * control its behavior with these fields:
+ * label:
+ * (required) Label to be shown next to the checkbox.
+ * checked:
+ * (optional) Whether the checkbox should be checked
+ * by default. Defaults to false.
+ * checkedState:
+ * (optional) An object that allows you to customize
+ * the notification state when the checkbox is checked.
+ * disableMainAction:
+ * (optional) Whether the mainAction is disabled.
+ * Defaults to false.
+ * warningLabel:
+ * (optional) A (warning) text that is shown below the
+ * checkbox. Pass null to hide.
+ * uncheckedState:
+ * (optional) An object that allows you to customize
+ * the notification state when the checkbox is not checked.
+ * Has the same attributes as checkedState.
+ * popupIconURL:
+ * A string. URL of the image to be displayed in the popup.
+ * Normally specified in CSS using list-style-image and the
+ * .popup-notification-icon[popupid=...] selector.
+ * learnMoreURL:
+ * A string URL. Setting this property will make the
+ * prompt display a "Learn More" link that, when clicked,
+ * opens the URL in a new tab.
+ * @returns the Notification object corresponding to the added notification.

+/*
+ * This module implements the front end behavior for AeroPeek. The taskbar
+ * allows an application to expose its tabbed interface by showing thumbnail
+ * previews rather than the default window preview.
+ * Additionally, when a user hovers over a thumbnail (tab or window),
+ * they are shown a live preview of the window (or tab + its containing window).
+ *
+ * In Windows 7, a title, icon, close button and optional toolbar are shown for
+ * each preview. This feature does not make use of the toolbar. For window
+ * previews, the title is the window title and the icon the window icon. For
+ * tab previews, the title is the page title and the page's favicon. In both
+ * cases, the close button "does the right thing."
+ *
+ * The primary objects behind this feature are nsITaskbarTabPreview and
+ * nsITaskbarPreviewController. Each preview has a controller. The controller
+ * responds to the user's interactions on the taskbar and provides the required
+ * data to the preview for determining the size of the tab and thumbnail. The
+ * PreviewController class implements this interface. The preview will request
+ * the controller to provide a thumbnail or preview when the user interacts with
+ * the taskbar. To reduce the overhead of drawing the tab area, the controller
+ * implementation caches the tab's contents in a <canvas> element. If no
+ * previews or thumbnails have been requested for some time, the controller will
+ * discard its cached tab contents.
+ *
+ * Screen real estate is limited so when there are too many thumbnails to fit
+ * on the screen, the taskbar stops displaying thumbnails and instead displays
+ * just the title, icon and close button in a similar fashion to previous
+ * versions of the taskbar. If there are still too many previews to fit on the
+ * screen, the taskbar resorts to a scroll up and scroll down button pair to let
+ * the user scroll through the list of tabs. Since this is undoubtedly
+ * inconvenient for users with many tabs, the AeroPeek objects turns off all of
+ * the tab previews. This tells the taskbar to revert to one preview per window.
+ * If the number of tabs falls below this magic threshold, the preview-per-tab
+ * behavior returns. There is no reliable way to determine when the scroll
+ * buttons appear on the taskbar, so a magic pref-controlled number determines
+ * when this threshold has been crossed.
