Hello,
I'm the author of Quaternion.js and derived a simpler method to rotate a vector using normalized quaternions, reducing the number of multiplications quite a bit. Since gl-matrix is developed with performance in mind, I think this addition can improve quite a few code bases.
All your unit tests are passing. I removed the performance test link, since jsPerf is offline for quite some time now.
