+/*
+ * 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.
