Robert has added an osgsimpleviewerSDL example to the latest CVS, and as
someone with lots of SDL+OSG experience I would highly recommend using
this as a basis. The union of the two really couldn't be simpler, so a
whole nodekit is probably not necessary. :)
I'm not sure to what depths the example goes to support resizing and
SceneView orthographic stuff, but it's easy enough to do that if the
osgGA::SimpleViewer doesn't. Maybe someone else can comment on this
aspect.
