* Add the Magnetic Lasso tool A selection border that snaps to edges as the pointer moves, in the Lasso (L) flyout after the Polygonal Lasso. - photocraft-algo `magnetic`: live-wire edge tracing (Mortensen & Barrett 1995): Sobel strength, non-maximum suppression and gradient direction link costs, a shortest path inside a corridor of the detection width around the pointer's path, sub-pixel edge centres. Pixels are read lazily in 128 px blocks. - Engine: `EdgeSource` (the active pixel layer, else the composite) and `select.magneticLasso`: rough points in, a border along the edges out; `trace: false` selects a given outline, which is how the tool commits. - UI: click to start, move to trace (button up or down), points fasten by themselves (Frequency), click fastens, Alt-click straight, Alt-drag freehand, Backspace/Delete removes points, click the first point, double-click or Enter closes, Esc cancels, [ ] change the width. Options bar: Width, Contrast, Frequency, tablet pressure. `ui.inspect` reports the border in progress. - The Lasso and Polygonal Lasso now apply the options bar's Feather; `select.lasso` rejects a feather outside 0..1000. - Icon adapted from Noun Project's "Magnetic Lasso Tool" by Lil' Seal (CC BY 3.0, licence file and ATTRIBUTION.md row).
