I am not having success viewing X3D html files generated with the -W option
in targen in either Firefox 46, Edge or Internet Explorer 11.
All three browsers report "Your browser supports X3DOM" when visiting
www.x3dom.org/check/ <http://www.x3dom.org/check/> yet none of them are
capable of displaying the X3D html files.
All I get are blank pages.
