/*
* nsIWinTaskbar
*
* This interface represents a service which exposes the APIs provided by the
* Windows taskbar to applications.
*
* Starting in Windows 7, applications gain some control over their appearance
* in the taskbar. By default, there is one taskbar preview per top level
* window (excluding popups). This preview is represented by an
* nsITaskbarWindowPreview object.
*
* An application can register its own "tab" previews. Such previews will hide
* the corresponding nsITaskbarWindowPreview automatically (though this is not
* reflected in the visible attribute of the nsITaskbarWindowPreview). These
* tab previews do not have to correspond to tabs in the application - they can
* vary in size, shape and location. They do not even need to be actual GUI
* elements on the window. Unlike window previews, tab previews require most of
* the functionality of the nsITaskbarPreviewController to be implemented.
*
* Applications can also show progress on their taskbar icon. This does not
* interact with the taskbar previews except if the nsITaskbarWindowPreview is
* made invisible in which case the progress is naturally not shown on that
* window.
*
* When taskbar icons are combined as is the default in Windows 7, the progress
* for those windows is also combined as defined here:
*
* Applications may also define custom taskbar jump lists on application shortcuts.
* See nsILegacyJumpListBuilder for more information.
