Matrix operations could be of more use than Scenic

[crertel]

Scenic uses a very limited version of matrix math (what you need for graphics), and doesn't implement all the operations one might be interested in. There are other libraries that target more general-purpose usage.

I like the spirit of your suggestion, but I don't think it's practical at this time.
