There are plenty of shapes, but if they were 2D primitives, perhaps they 
could be optimized for better performance. Especially for making an 
animation. But then, that would be getting away from the core of what POV 
is.

I use it for 2D work not because it's necessarily the best choice or the 
fastest, but I already know the SDL really well, and I'm not familiar with 
any script based plotting and graphing engines.

I did play around with using XNA to do real time animated 3D plots, but I 
never did find it to be worth the trouble. Honestly, if you're going to roll 
your own that way, it's just as easy to call the managed DirectX assemblies 
yourself. (Yes, I can program in C++ or even x86 assembler, but sometimes 
letting the computer do the work for me gives me more time to play...)
