In some contexts, the "DOM" in DOMMatrix feels out of place, for example in WebGL. Why not call it something like TransformationMatrix, GraphicalMatrix, Matrix3D, or something more generic like that so the name is agnostic of where you are using the class. I'm not manipulating DOM inside of a WebGL context.
I made discussion about this on Discourse: http://discourse.wicg.io/t/the-name-of-dommatrix-is-out-of-place/1169 - Joe */#!/*JoePea
