A gradient fitted to the object refit to the outline after the object's Transform effect rotated, reflected or scaled it unevenly, so the gradient kept running left to right while the shape turned under it. Object › Transform already turns such a gradient. A Transform effect that a refit would not reproduce now fixes the gradient to its fit on the geometry the effect takes, and then maps it with that effect and the effects after it, as a placed gradient. Under moves and even scales it draws as a refit does, and an effect that scales the object to nothing across leaves it fitted. This applies to an object's own effects, a fill's or stroke's own effects, and a group's: in a group, the gradients fitted to its paths, to its own fill, to the groups inside it and to its images' and symbol instances' own fills each fix to the fit on their own object. Object › Expand of the fill draws the same. This changes how existing documents draw: art with a fitted gradient and a Transform effect that rotates, reflects or scales it unevenly now shows the gradient turned with the art. How gradients follow the effect is VectorCraft's own rule.
