Meanwhile, at the other end of the scale, you have a system with the capabilities of the Javascript DOM (see above), or the Flash player. This system can composite multiple 2D layers, and keep track of the contents of those layers.
Yes, this is the scene graph approach. This is basically SVG, a hierarchy of transforms, shapes and interactive nodes. A retained mode version of Display Postscript. Although OpenInventor has a more powerful model, perhaps (Coin3D is freely available as a starting point).
The Flash model is formalized as as a DOM in StageXL: http://www.stagexl.org/
Another scene graph that was used in X11 servers is PHIGS.
