This is intended for usage with frameless windows that show the standard window buttons, where resizing the title bar height changes the button offset. Returning a different value from CefWindowDelegate::GetTitlebarHeight and forcing a resize of the NSWindow's theme frame (see ViewsWindow::NudgeWindow) will update the title bar height. To test: 1. Run `cefclient --use-views --hide-frame --show-window-buttons --url=http://tests/window` 2. Enter a new value for title bar height and click the "Set Titlebar Height" button
