410// Fullscreen terminology:
411//
412// ----------------------------------------------------------------------------
413// There are 2 APIs that cause the window to get resized, and possibly move
414// spaces.
415//
416// + AppKitFullscreen API: AppKit touts a feature known as "fullscreen". This
417// involves moving the current window to a different space, and resizing the
418// window to take up the entire size of the screen.
419//
420// + Immersive fullscreen: An alternative to AppKitFullscreen API. Uses on 10.6
421// (before AppKitFullscreen API was available), and on certain HTML/Flash
422// content. This is a method defined by Chrome.
423//
424// The Immersive fullscreen API can be called after the AppKitFullscreen API.
425// Calling the AppKitFullscreen API while immersive fullscreen API has been
426// invoked causes all fullscreen modes to exit.
427//
428// ----------------------------------------------------------------------------
429// There are 2 "styles" of omnibox sliding.
430// + OMNIBOX_TABS_PRESENT: Both the omnibox and the tabstrip are present.
431// Moving the cursor to the top causes the menubar to appear, and everything
432// else to slide down.
433// + OMNIBOX_TABS_HIDDEN: Both tabstrip and omnibox are hidden. Moving cursor
434// to top shows tabstrip, omnibox, and menu bar.
435//
436// The omnibox sliding styles are used in conjunction with the fullscreen APIs.
437// There is exactly 1 sliding style active at a time. The sliding is mangaged
438// by the presentationModeController_. (poorly named).
439//
440// ----------------------------------------------------------------------------
441// There are several "fullscreen modes" bantered around. Technically, any
442// fullscreen API can be combined with any sliding style.
443//
444// + System fullscreen***deprecated***: This term is confusing. Don't use it.
445// It either refers to the AppKitFullscreen API, or the behavior that users
446// expect to see when they click the fullscreen button, or some Chrome specific
447// implementation that uses the AppKitFullscreen API.
448//
449// + Canonical Fullscreen: When a user clicks on the fullscreen button, they
450// expect a fullscreen behavior similar to other AppKit apps.
451//  - AppKitFullscreen API + OMNIBOX_TABS_PRESENT.
452//  - The button click directly invokes the AppKitFullscreen API. This class
453//  get a callback, and calls adjustUIForOmniboxFullscreen.
454//  - There is a menu item that is intended to invoke the same behavior. When
455//  the user clicks the menu item, or use its hotkey, this class invokes the
456//  AppKitFullscreen API.
457//
458// + Presentation Mode:
459//  - OMNIBOX_TABS_HIDDEN, typically with AppKitFullscreen API, but can
460//  also be with Immersive fullscreen API.
461//  - This class sets a flag, indicating that it wants Presentation Mode
462//  instead of Canonical Fullscreen. Then it invokes the AppKitFullscreen API.
463//
464// + HTML5 fullscreen. <-- Currently uses AppKitFullscreen API. This should
465// eventually migrate to the Immersive Fullscreen API.
466//
467// There are more fullscreen styles on OSX than other OSes. However, all OSes
468// share the same cross-platform code for entering fullscreen
469// (FullscreenController). It is important for OSX fullscreen logic to track
470// how the user triggered fullscreen mode.
471// There are currently 5 possible mechanisms:
472//   - User clicks the AppKit Fullscreen button.
473//     -- This invokes -[BrowserWindowController windowWillEnterFullscreen:]
474//   - User selects the menu item "Enter Full Screen".
475//     -- This invokes FullscreenController::ToggleFullscreenModeInternal(
476//        BROWSER_WITH_CHROME)
477//   - User selects the menu item "Enter Presentation Mode".
478//     -- This invokes FullscreenController::ToggleFullscreenModeInternal(
479//        BROWSER)
480//     -- The corresponding URL will be empty.
481//   - User requests fullscreen via an extension.
482//     -- This invokes FullscreenController::ToggleFullscreenModeInternal(
483//        BROWSER)
484//     -- The corresponding URL will be the url of the extension.
485//   - User requests fullscreen via Flash or JavaScript apis.
