I don't think it belongs here, since it has nothing to do with resources. Could
we put it on the GLRenderer?

Oh, ya ok I'll give that a shot. The one problem I was trying to dodge is that
it has to go thru the Renderer class API which includes software mode. So then
passing a WGC3D thru there is weird.. ideas about that?
