Smooth and Feather: crop to the selection, up to 395× faster on small selections
Smooth and Feather: crop to the selection, up to 395× faster on small selections Smooth and Feather still read and replaced full-canvas masks, even for tiny selections. On a 6000×6000 canvas, each `f32` plane is 144 MB. The blur kernels already limited their work to the nonzero region, but mask conversion and replacement still involved the whole canvas. ## Change - Both commands use the selection window from #9697 for mask reads, algorithm input/output and tiled replacement. - Smooth grows the nonzero bounds by `ceil(radius) + 1`. Feather uses the blur's shared `selection::feather_reach(radius)` plus one pixel: `ceil(3 * radius) + 1` for accepted radii. Both windows are
