.str()

gl-matrix converts things to strings. See: http://glmatrix.net/docs/vec2.js.html#line468. I'm not in love with the function, but maybe makes sense to add and be done with it.

Specifically, I like numpy's approach of making the output valid input, which would suggest making require('gl-vec2) an alias for vec2.fromValues so that the output vec2(1.0, 2.0) would also be valid input. That might be too fancy though.
