Use twgl-base instead of twgl?

[paulkaplan]

It looks like the webgl library TWGL comes in two flavors, the full and the base. We are using full, which includes 3d geometry primitives and 3d matrix math, both of which i don't think we are using. We should be able to switch to twgl-base.js and save 150k over the full library

We actually do use the matrix math from TWGL, mostly in Drawable, but it still might make sense to switch. We could use twgl-base.js along with, say, gl-matrix for the matrix math, for example. I'll do some time and space benchmarks :)
