Gradients left a radial gradient as bands. An area whose colour does not go along one direction is now tried as a radial gradient: the middle is the common middle of the circles its pixels of one tone lie on (three tones, which must agree within 3 px), the stops are read outwards from it (`TracedGradient::radial`; a radial gradient fill in the document). Harness: a radial-gradient input with known middle and stops; a gradient counts as found only if it is of the input's kind. Radial input with Gradients on: found in all 7 drawings, 0 to 1 path beside it (8 to 15 without); dE 2.69 -> 0.25 (6 Colors, clean), 0.80 -> 0.25 (High Fidelity Photo). The linear inputs are as they are without this. No gradient on any input that is flat colour.
