cef/tests/cefclient/browser/root_window_gtk.cc
Marshall Greenblatt faa85bf980 Support JavaScript window.moveTo/By() and resizeTo/By() (fixes #698) 
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.
