/*
* nsITaskbarWindowPreview
*
* This interface represents the preview for a window in the taskbar. By
* default, Windows implements much of the behavior for applications by
* default. The primary purpose of this interface is to allow Gecko
* applications to take control over parts of the preview. Some parts are not
* controlled through this interface: the title and icon of the preview match
* the title and icon of the window always.
*
* By default, Windows takes care of drawing the thumbnail and preview for the
* application however if enableCustomDrawing is set to true, then the
* controller will start to receive drawPreview and drawThumbnail calls as well
* as reads on the thumbnailAspectRatio, width and height properties.
*
* By default, nsITaskbarWindowPreviews are visible. When made invisible, the
* window disappears from the list of windows in the taskbar for the
* application.
*
* If the window has any visible nsITaskbarTabPreviews, then the
* nsITaskbarWindowPreview for the corresponding window is automatically
* hidden. This is not reflected in the visible property. Note that other parts
* of the system (such as alt-tab) may still request thumbnails and/or previews
* through the nsITaskbarWindowPreview's controller.
*
* nsITaskbarWindowPreview will never invoke the controller's onClose or
* onActivate methods since handling them may conflict with other internal
* Gecko state and there is existing infrastructure in place to allow clients
* to handle those events
*
* Window previews may have a toolbar with up to 7 buttons. See
* nsITaskbarPreviewButton for more information about button properties.
