I've been so blind. The idea of using a scene graph for two-dimensional graphics never got into my skull until earlier this month. It's been around for quite some time, but I never made the connection myself. Scene graphs are used all the time in three-dimensional gaming, but for 2D apps, it looks like it is used, but not as much as it can be.
This Scene graph article on GameDev does a pretty good job at explaining why they are so cool.
I was originally going to put a long paragraph here on all the examples of how it could benefit us, but I've forgotten what they were. Just remember that at one time I thought they were really useful.
The End.
