Detailed Description

Basic NodeVisitor implementation for rendering a scene. This visitor traverses the scene graph, collecting transparent and opaque osg::Drawables into a depth sorted transparent bin and a state sorted opaque bin. The opaque bin is rendered first, and then the transparent bin is rendered in order from the furthest osg::Drawable from the eye to the one nearest the eye.
