2. would work, and a variant on that is to derive your own Drawable and
override drawImplementation() to issue your OpenGL calls. Again, you'd have
to assign a max render bin number to the Drawable's StateSet.
> I have some 3rd party OGL code that needs to draw (add some 2D/3D
> decorations) directly to the framebuffer after everything
> else is drawn (i.e. right before swapBuffers).
> What would be the best way to do this:
> 1. add a call in Viewbase.cpp to call the 3rd party draw()
> method right before swapBuffers().
> 2. a draw callback on a scenegraph node assigned to the
> highest number render bin.
> 3. other ways?
