// This class allows us to exercise control over the window's title bar. It is
// used for all windows with titlebars.
//
// ToolbarWindow supports two modes:
// - drawsContentsIntoWindowFrame mode: In this mode, the Gecko ChildView is
// 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 TitlebarGradientView
// 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 TitlebarGradientView,
// 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
// -moz-appearance rendering of the toolbar.
