* Add the Patch tool (#213) paint.patch heals the selected area with texture from where the selection is dragged (Source) or copies the selection onto the dragged-to area (Destination), seamless-cloned like the Healing Brush. The solve is clipped to the canvas, so patches at the edge stay opaque. Tool::Patch joins the J group: outside the selection it draws a lasso (Shift/Alt add/subtract), inside it drags the patch, the outline follows the pointer and the offset is clamped to the canvas. Options bar: Source / Destination. Strings translated in all six catalogs. Tests at 8/16/32 bit, a UI gesture test, panic_hunt green. Scorecard TOOL-213-3 is partial: the drag previews the outline, not the pixels. retouch_bench: patch 250x250 22 ms, 1000x1000 362 ms (release). generated with Claude Code * Patch tool: live preview of the heal while dragging (#213) The canvas shows the document healed at the pointer's offset (patch_preview.rs, modelled on the Move tool's preview) and recomposites only the healed area; release commits the exact paint.patch and its damage rect refreshes the same area. The preview (retouch_cmds::patch_preview) solves the colour fit on a coarse grid (at most 128x128 cells) and interpolates it back: the Poisson result is source + a harmonic correction, so the texture stays exact and only the smooth correction is approximated (worst pixel 0.022 at 8x coarser in the test). Selection coverage is read tile-wise and the interpolation runs per row in parallel. retouch_bench (release, 6016x6016): preview 250x250 7 ms, 500x500 17 ms, 1000x1000 52 ms (exact patch: 21 / 90 / 354 ms). Scorecard TOOL-213-3 done. Also applies rustfmt to the first commit's code. generated with Claude Code * Patch tool: cap patches at 16M pixels, drop product names from comments (#213) The solve needs roughly 150 bytes per pixel, so the old 64M cap allowed about 10 GB and risked an allocation abort instead of an error. generated with Claude Code * Regenerate docs/scorecard.md Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Tool::ALL holds both the Patch tool and the Mixer Brush (rebase onto #433) Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> --------- Co-authored-by: Brandon Thomas <echelon@gmail.com> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>
