warp_point worked on box coordinates normalised to -1..1 on both axes: Arc's radius was in x units but its edges were offset in y units, so a box that isn't square bent into no circular arc (skewed sides from Bend 10 %), and at 100 % the radius (2/π) was smaller than the half-height, folding the inner edge over. warp_point now takes the box's aspect along the warp; Arc keeps the centre line's length on a circular arc in real proportions, with concentric edges, and an inner edge that would pass the centre stops there. Other styles are as they were; a square is bent as before. Fixes #1578 |
