In the description for SVGMatrix.rotateFromVector, it is stated that
BOTH of the supplied vector coordinates must be non-zero. Shouldn't the
restriction be instead that AT LEAST ONE of the coordinates must be
non-zero? After all, rotations of 0, 90, 180 and 270 degrees correspond
to rotation vectors of (1, 0), (0, 1), (-1, 0) and (0, -1),
respectively.
