pub fn affine_to_canvas_params(affine: Affine) -> [f64; 6]Expand description
Decomposes a plotkit Affine transform into the six parameters
expected by CanvasRenderingContext2d.setTransform(a, b, c, d, e, f).
The kurbo Affine stores its coefficients as [a, b, c, d, e, f] where
the matrix is:
| a c e |
| b d f |
| 0 0 1 |Canvas2D setTransform expects (a, b, c, d, e, f) with the same layout.
