+// sized to cover the entire window frame and manages titlebar drawing.
+// - separate titlebar mode, with support for unified toolbars: In this mode,
+// the Gecko ChildView does not extend into the titlebar. However, this
+// window's content view (which is the ChildView's superview) *does* extend
+// into the titlebar. Moreover, in this mode, we place a MOZTitlebarView
+// in the content view, as a sibling of the ChildView.
+//
+// The "separate titlebar mode" supports the "unified toolbar" look:
+// If there's a toolbar right below the titlebar, the two can "connect" and
+// form a single gradient without a separator line in between.
+//
+// The following mechanism communicates the height of the unified toolbar to
+// the ToolbarWindow:
+//
+// 1) In the style sheet we set the toolbar's -moz-appearance to toolbar.
+// 2) When the toolbar is visible and we paint the application chrome
+// window, the array that Gecko passes nsChildView::UpdateThemeGeometries
+// will contain an entry for the widget type StyleAppearance::Toolbar.
+// 3) nsChildView::UpdateThemeGeometries passes the toolbar's height, plus the
+// titlebar height, to -[ToolbarWindow setUnifiedToolbarHeight:].
+//
+// The actual drawing of the gradient happens in two parts: The titlebar part
+// (i.e. the top 22 pixels of the gradient) is drawn by the MOZTitlebarView,
+// which is a subview of the window's content view and a sibling of the ChildView.
+// The rest of the gradient is drawn by Gecko into the ChildView, as part of the
