// A class that works as a custom titlebar for Panels. It is placed on top of
// the regular Cocoa titlebar. It's the place for the close button, page
// favicon, title label and a button to minimize/restore the panel.
// It also facilitates dragging and minimization of the panels, and changes
// color as 'new activity' indicator.
// One way to have custom titlebar would be to use NSBorderlessWindow,
// but it seems to affect too many other behaviors (for example, it draws shadow
// differently based on being key window) so it appears easier to simply overlay
// the standard titlebar.
// This view overlays the titlebar on top. It is used to intercept
// mouse input to prevent reordering of the other browser windows when clicking
// on the titlebar (to minimize or reorder) while in a docked collection.
