+ *
+ * If you're developing a feature that requires web content to ask
+ * for special permissions from the user, this module is for you.
+ *
+ * Suppose a system add-on wants to add a new prompt for a new request
+ * for getting more low-level access to the user's sound card, and the
+ * permission request is coming up from content by way of the
+ * nsContentPermissionHelper. The system add-on could then do the following:
+ *
+ * Cu.import("resource://gre/modules/Integration.jsm");
+ * Cu.import("resource:///modules/PermissionUI.jsm");
+ *
+ * const SoundCardIntegration = (base) => ({
+ * __proto__: base,
+ * createPermissionPrompt(type, request) {
+ * if (type != "sound-api") {
+ * return super.createPermissionPrompt(...arguments);

+ * // a better idea of what things one can and should override.
+ * }

+ * });
+ *
+ * // Add-on startup:
+ * Integration.contentPermission.register(SoundCardIntegration);
+ * // ...
+ * // Add-on shutdown:
+ * Integration.contentPermission.unregister(SoundCardIntegration);
+ *
+ * Note that PermissionPromptForRequestPrototype must be used as the
+ * prototype, since the prompt is wrapping an nsIContentPermissionRequest,
+ * and going through nsIContentPermissionPrompt.
+ *
+ * It is, however, possible to take advantage of PermissionPrompt without
+ * having to go through nsIContentPermissionPrompt or with a
+ * nsIContentPermissionRequest. The PermissionPromptPrototype can be
+ * imported, subclassed, and have prompt() called directly, without

+/*
+ * This module implements the front end behavior for AeroPeek. Starting in
+ * Windows Vista, the taskbar began showing live thumbnail previews of windows
+ * when the user hovered over the window icon in the taskbar. Starting with
+ * Windows 7, the taskbar allows an application to expose its tabbed interface
+ * in the taskbar 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.
