Unless there's a bug it should just be either a Float32Array
or a standard JavaScript array
var some9ElementJSArray = [1, 2, 3, 4, 5, 6, 7, 8, 9];
var some9ElementFloat32Array = new Float32Array([11, 12, 13, 14, 15, 16, 17, 18, 19]);
twgl.setUniforms(someProgramInfo, {
someMat3Uniform: some9ElementJSArray,
someOtherMat3Uniform: some9ElementFloat32Array,
});

Thanks. I was thinking of starting to write up an m3.js, but that's probably overkill. I'm using a normal matrix as in http://graphics.cs.wisc.edu/WP/cs559-fall2016/2016/11/02/how-to-compute-a-normalmatrix-in-twgl/ ... it's too bad about the extra calculations inverting a 4x4 matrix when only a 3x3 matrix is needed.
