+Opens given URL and returns {\tt wxFSFile} object that can be used to read data

+
+Always use this method in tag handlers instead of {\tt GetFS()->OpenFile()} 
+because it can block the URL and is thus more secure.
+
+Default behaviour is to call \helpref{wxHtmlWindow::OnOpeningURL}{wxhtmlwindowonopeningurl}
+of the associated wxHtmlWindow object (which may decide to block the URL or
+redirect it to another one),if there's any, and always open the URL if the 
+parser is not used with wxHtmlWindow.

+Returned {\tt wxFSFile} object is not guaranteed to point to {\it url}, it might
+have been redirected!
