-/**
- * ContentSearch receives messages named INBOUND_MESSAGE and sends messages
- * named OUTBOUND_MESSAGE.  The data of each message is expected to look like
- * { type, data }.  type is the message's type (or subtype if you consider the
- * type of the message itself to be INBOUND_MESSAGE), and data is data that is
- * specific to the type.
- *
- * Inbound messages have the following types:
- *
- *   AddFormHistoryEntry
- *     Adds an entry to the search form history.
- *     data: the entry, a string
- *   GetSuggestions
- *     Retrieves an array of search suggestions given a search string.
- *     data: { engineName, searchString, [remoteTimeout] }
- *   GetState
- *     Retrieves the current search engine state.
- *     data: null
- *   GetStrings
- *     Retrieves localized search UI strings.
- *     data: null
- *   ManageEngines
- *     Opens the search engine management window.
- *     data: null
- *   RemoveFormHistoryEntry
- *     Removes an entry from the search form history.
- *     data: the entry, a string
- *   Search
- *     Performs a search.
- *     Any GetSuggestions messages in the queue from the same target will be
- *     cancelled.
- *     data: { engineName, searchString, healthReportKey, searchPurpose }
- *   SetCurrentEngine
- *     Sets the current engine.
- *     data: the name of the engine
- *   SpeculativeConnect
- *     Speculatively connects to an engine.
- *     data: the name of the engine
- *
- * Outbound messages have the following types:
- *
- *   CurrentEngine
- *     Broadcast when the current engine changes.
- *     data: see _currentEngineObj
- *   CurrentState
- *     Broadcast when the current search state changes.
- *     data: see currentStateObj
- *   State
- *     Sent in reply to GetState.
- *     data: see currentStateObj
- *   Strings
- *     Sent in reply to GetStrings
- *     data: Object containing string names and values for the current locale.
- *   Suggestions
- *     Sent in reply to GetSuggestions.
- *     data: see _onMessageGetSuggestions
- *   SuggestionsCancelled
- *     Sent in reply to GetSuggestions when pending GetSuggestions events are
- *     cancelled.
- *     data: null

- * PermissionUI is responsible for exposing both a prototype
- * PermissionPrompt that can be used by arbitrary browser
- * components and add-ons, but also hosts the implementations of
- * built-in permission prompts.
- *
- * 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);
- *     }
- *
- *     return {
- *       __proto__: PermissionUI.PermissionPromptForRequestPrototype,
- *       get permissionKey() {
- *         return "sound-permission";
- *       }
- *       // etc - see the documentation for PermissionPrompt for
- *       // 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
- * the caller having called into createPermissionPrompt.

-/*
- * 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.
