Adds new CefDisplayHandler::OnContentsBoundsChange and CefDisplayHandler::GetRootWindowScreenRect callbacks. cefclient: Implement the above callbacks and call CefBrowserHost::NotifyScreenInfoChanged when the root window bounds change. cefclient: osr: Use real screen bounds by default. Pass `--fake-screen-bounds` for the old default behavior. Load https://tests/window in cefclient for additional implementation details and usage examples.

// When using GTK in multi-threaded mode you must do the following:
|

// 1. Call gdk_threads_init() before making any other GTK/GDK/GLib calls.

// 2. Acquire the global lock before making any GTK/GDK calls, and release the

|
// lock afterwards. This should only be done with callbacks that do not
|
|
// originate from GTK signals (because those callbacks already hold the

|
// lock).
