doClose

Called when a browser has received a request to close. If CEF created an OS window for the browser returning false will send an OS close notification to the browser window's top-level owner (e.g. WM_CLOSE on Windows, performClose: on OS-X and "delete_event" on Linux). If no OS window exists (window rendering disabled) returning false will cause the browser object to be destroyed immediately. Return true if the browser is parented to another window and that other window needs to receive close notification via some non-standard technique.
