-// Provides a controller to manage fullscreen mode for a single browser window.
-// This class handles running animations, showing and hiding the floating
-// dropdown bar, and managing the tracking area associated with the dropdown.
-// This class does not directly manage any views -- the BrowserWindowController
-// is responsible for positioning and z-ordering views.
-//
-// Tracking areas are disabled while animations are running.  If
-// |overlayFrameChanged:| is called while an animation is running, the
-// controller saves the new frame and installs the appropriate tracking area
-// when the animation finishes.  This is largely done for ease of
-// implementation; it is easier to check the mouse location at each animation
-// step than it is to manage a constantly-changing tracking area.
