Copy constructors

> See my response to Greg.  I don't currently process SVG at runtime.  I just think it makes the API more generic if that case is supported better.  I don't see why the current FXMLLoader should be limited the way it currently is.

I'm sorry - I don't understand what limitation you are referring to. 

Keep in mind that FXMLLoader's sole purpose is loading FXML. It doesn't know about (and thus can't be optimized for loading) any other data format such as SVG. As I suggested earlier - if you want to efficiently load SVG, use an SVG-specific loader.
