Review follow-ups, tests only.
- The Pencil test and the `vector.simplify` test measure how far the result
strays from the samples (at most 1.5), not only its box.
- The Pencil test also draws with the Marker and the Highlighter, each stroke
in a fresh session, and takes the layer that stroke made.
- The `vector.simplify` test runs on an open stroke, a filled shape, a region
with its own fill, and a stroke beside a filled shape.
- The geom tests run at accuracies 0.1, 0.75 and 8.0, on quadratic and cubic
inputs as well as lines, and check both ways round how far the result and
the input are apart.
- A path that turns straight back is checked to be kurbo's fit of each side on
its own, with a point at the turn.
- Empty paths, lone moves and segments after a close are covered.
kurbo's simplify_bezpath, which smooths Pencil samples and runs Simplify
path, fitted two common shapes with a curve that ran far off the path: a
stroke that goes out and back to the very point it left (kurbo keeps a
reversal as a smooth join) and nearly collinear samples (kurbo measures
its error across the path, not along it).
figcraft_geom::simplify_path cuts the path where it turns back by more
than a right angle, simplifies each run with kurbo, and keeps a run as it
was when its fit strays more than twice the accuracy from it. The Pencil
and vector.simplify use it.
vector.simplify and vector.offset rebuild a closed vector from its rounded
outline with the layer's corner smoothing, as the canvas draws it. A vector
whose regions have paints of their own was rebuilt from its sharp points
before; it now keeps its rounded corners. The Penpot export writes a stroked
vector's path with its smoothed corners.
Retain regional paint stacks and coordinate frames through simplify, offset, flatten, bucket normalization and Shape Builder. Preserve legacy fill semantics and synchronize importer warning catalogs. Verified with cargo xtask ci on Windows and Ubuntu/WSL, native UI screenshots, and CLI round-trip/export checks.
Review follow-up. A file written by this version carries editorOutlines, so a stroke someone chose is kept even when it matches the old decoration; only files without the marker get the one-time legacy cleanup. vector.create now errors when a requested side cannot scale the geometry or when both axes would collapse, instead of creating an invisible layer.
A path's intrinsic box replaced the width and height asked for, so an icon imported at 24 stayed on its source grid. Scale the geometry to the requested size; with one side the other keeps its proportion. A path or point set that draws nothing is an error now, not an invisible 0x0 layer.
A 1 px Line or stroke-only path only counted as hit within 2 screen
pixels, so a double-click slightly off it cleared the selection and
never entered vector edit mode, and Cmd/Ctrl could not bend it.
Strokes with nothing filled now reach 5 screen pixels; filled shapes
keep the plain tolerance.
A filled area of a vector network can now carry its own paint stack. A region without paints of its own keeps drawing with the layer's fills, and a region with an explicitly empty list draws nothing, so the two cases stay distinguishable. The canvas, SVG and PDF output, boolean and hit-test geometry, vector editing and region operations all honour the per-region paints and keep them when regions are split, merged or reordered.
The .fig importer resolves the individual paint stacks of a layer's filled areas through its normal paint mapping and hands them to the document builder as private mapper data. Public REST vectorNetwork JSON never consumes that data and its region paints are dropped, so only validated .fig input can set them. Invalid entries are skipped with an import note. Live style and variable links on individual regions and writing region paints in the experimental .fig exporter are not part of this change.
**A shapes and vector behaviour suite written from the public documentation, and fixes for every divergence it found.** Each documented rule (drawing with Shift and Alt, corner radius and which layers take one, point counts and star ratios, arcs, stroke joins and the miter angle, caps per end, boolean results and the look they take, flatten and outline stroke; entering and leaving vector edit mode, the pen, selecting points and segments, deleting vs. delete and heal, handle mirroring, the bend, paint bucket, cut, join and eraser tools, nudging and undo steps, what converting a shape keeps) is a table row or a step with what the rule implies and a one-line derivation; where the documentation is silent the row says so and pins today's behaviour.
**Fixes**
- **Rounded vector points were stored but never drawn**: a point's corner radius (edit mode's Corner radius field, `vector.edit.cornerRadius`) now rounds the corner between two straight segments on the canvas, in hit testing, booleans and every export (`VectorNetwork::rounded`, used by the fill and stroke paths); the radius shrinks to fit half of each segment, like a polygon's corners. A vector layer's own corner radius rounds every point. The points stay where they are in edit mode.
- **A boolean group's look follows its operation**: union, intersect and exclude take the top layer's fills, strokes and effects, subtract the bottom layer's (it was always the bottom one).
- **Alt draws a line or an arrow from its centre**, like the other shapes (it was ignored).
- **Stars keep to 3–60 points** (they went to 120; polygons keep 120, the documentation is silent); a junk `pointCount` is refused instead of becoming 5.
- **Delete and heal recomputes the curve**: the healed segment keeps its neighbours' tangents and passes through where the deleted point was (it reused the neighbours' handles, so healing over a circle cut deep inside it). Corners between straight segments heal straight, as before.
- **Shift-click on a selected point at a corner of the points' transform box takes it out of the selection** (it started a scale); a Shift-drag there still scales in proportion.
- **Outline stroke** turns the stroke's colour style into the outline's fill style, and the outline keeps the layer's opacity, blend, effects, constraints and visibility (they were lost).
- **The stroke panel's Miter angle shows degrees** (it showed the ratio 4 under that name; the default is ~28.96°); `node.set {miterAngle}` sets it and `get_node` reports a non-default join or angle.
- **Individual corners only for rectangles and frames**: polygons, stars and vectors have one radius (the toggle showed for them and set corners that weren't drawn).
- **Option/Alt+Shift+F flattens** (Cmd/Ctrl+E still does).
- **MCP `key` in vector edit mode reaches the edit tools first**, as the canvas does: tool letters, arrows, Delete / Shift+Delete, Cmd/Ctrl+J, Enter (Delete removed the whole layer; `X` was unknown).
**Missing documented behaviour, added**
- **Corner radius and star ratio handles on the canvas**: a handle inside each corner of a selected rectangle or frame, one inside a polygon's or star's top point, a ratio handle on a star's first inner point (`shape_handles.rs`). Dragging along a corner's bisector sets the radius of every corner (Alt: only that corner of a rectangle or frame, documentation silent), stopping where the corners meet; the ratio handle sets the inner radius. A readout shows the value while dragging; the handles hide under 48 px on screen, on locked layers, with several layers selected and in edit mode. One undo step per drag; `inspect_ui` lists them under `tool.shapeHandles`.
- **Count and Ratio fields** in the Design panel for polygons and stars (there was no way to change them in the UI).
- **Cut tool drags**: dragging across paths cuts them where the line crosses; parts that come apart move to layers of their own, each keeping its piece of the fill (`vector.edit.cut {from, to}`). A click still splits at a point or segment.
- **Paint bucket drags**: a drag fills or unfills every area it crosses the way the first one went (`vector.edit.paint {points}`), one undo step.
New strings go through `tr(...)` (the new fields reuse the existing Count / Ratio / Radius / Star / Polygon entries in `en.toml` and `es.toml`); the new fields have accessible names (an icon lead with its label). Each gesture and edit stays one undo step.
