glTF TRS matrix builder

Build a node’s column-major matrix from translation, quaternion and scale.

Example result

Compose T × R × S. The output array lists matrix columns, with translation in elements 12–14.

Identity rotation, scale (2,3,4) and translation (1,2,3) produce diagonal values 2,3,4,1 and the stated translation.

Quaternion length must be within 0.000001 of one. This builds local transforms; parent transforms and skinning are excluded.
