patch: set renderqueue for mygui

so, i added the ability to say mygui in what renderqueue it should render, see attached patch.

finally, we are able to render MyGUI in front of Ogre overlays

Yeah, thank you. I noticed it in redmine already.

Thanks. Good feature, But If can set renderquery group for each layer or even widget, may more great--> then able to blend normal Ogre scenenodes and mygui.

so, i added the ability to say mygui in what renderqueue it should render, see attached patch.

finally, we are able to render MyGUI in front of Ogre overlays

if you only need this, you could also put mygui on a transparent viewport on top of your other viewport(s)
