// Fullscreen terminology:
//
// ----------------------------------------------------------------------------
// There are 2 APIs that cause the window to get resized, and possibly move
// spaces.
//
// + AppKitFullscreen API: AppKit touts a feature known as "fullscreen". This
// involves moving the current window to a different space, and resizing the
// window to take up the entire size of the screen.
//
// + Immersive fullscreen: An alternative to AppKitFullscreen API. Uses on 10.6
// (before AppKitFullscreen API was available), and on certain HTML/Flash
// content. This is a method defined by Chrome.
//
// The Immersive fullscreen API can be called after the AppKitFullscreen API.
// Calling the AppKitFullscreen API while immersive fullscreen API has been
// invoked causes all fullscreen modes to exit.
//
// ----------------------------------------------------------------------------
// There are 2 "styles" of omnibox sliding.
// + OMNIBOX_TABS_PRESENT: Both the omnibox and the tabstrip are present.
// Moving the cursor to the top causes the menubar to appear, and everything
// else to slide down.
// + OMNIBOX_TABS_HIDDEN: Both tabstrip and omnibox are hidden. Moving cursor
// to top shows tabstrip, omnibox, and menu bar.
//
// The omnibox sliding styles are used in conjunction with the fullscreen APIs.
// There is exactly 1 sliding style active at a time. The sliding is mangaged
// by the presentationModeController_. (poorly named).
//
// ----------------------------------------------------------------------------
// There are several "fullscreen modes" bantered around. Technically, any
// fullscreen API can be combined with any sliding style.
//
// + System fullscreen***deprecated***: This term is confusing. Don't use it.
// It either refers to the AppKitFullscreen API, or the behavior that users
// expect to see when they click the fullscreen button, or some Chrome specific
// implementation that uses the AppKitFullscreen API.
//
// + Canonical Fullscreen: When a user clicks on the fullscreen button, they
// expect a fullscreen behavior similar to other AppKit apps.
//  - AppKitFullscreen API + OMNIBOX_TABS_PRESENT.
//  - The button click directly invokes the AppKitFullscreen API. This class
//  get a callback, and calls adjustUIForOmniboxFullscreen.
//  - There is a menu item that is intended to invoke the same behavior. When
//  the user clicks the menu item, or use its hotkey, this class invokes the
//  AppKitFullscreen API.
//
// + Presentation Mode:
//  - OMNIBOX_TABS_HIDDEN, typically with AppKitFullscreen API, but can
//  also be with Immersive fullscreen API.
//  - This class sets a flag, indicating that it wants Presentation Mode
//  instead of Canonical Fullscreen. Then it invokes the AppKitFullscreen API.
//
// + HTML5 fullscreen. <-- Currently uses AppKitFullscreen API. This should
// eventually migrate to the Immersive Fullscreen API.
//
// There are more fullscreen styles on OSX than other OSes. However, all OSes
// share the same cross-platform code for entering fullscreen
// (FullscreenController). It is important for OSX fullscreen logic to track
// how the user triggered fullscreen mode.
// There are currently 5 possible mechanisms:
//   - User clicks the AppKit Fullscreen button.
//     -- This invokes -[BrowserWindowController windowWillEnterFullscreen:]
//   - User selects the menu item "Enter Full Screen".
//     -- This invokes FullscreenController::ToggleFullscreenModeInternal(
//        BROWSER_WITH_CHROME)
//   - User selects the menu item "Enter Presentation Mode".
//     -- This invokes FullscreenController::ToggleFullscreenModeInternal(
//        BROWSER)
//     -- The corresponding URL will be empty.
//   - User requests fullscreen via an extension.
//     -- This invokes FullscreenController::ToggleFullscreenModeInternal(
//        BROWSER)
//     -- The corresponding URL will be the url of the extension.
//   - User requests fullscreen via Flash or JavaScript apis.
//     -- This invokes FullscreenController::ToggleFullscreenModeInternal(
//        BROWSER)
//     -- browser_->fullscreen_controller()->
//        IsWindowFullscreenForTabOrPending() returns true.
//     -- The corresponding URL will be the url of the web page.
