- a_faces_seam_stays_within_half_its_width_of_the_face checks Rotate
(Classic)'s branches too: No Shading keeps its paint, a gradient keeps
the gradient, and Diffuse shades its plane darker at some view.
- classic_revolves_seams_are_round checks each seam's reach as well as
its join, and covers a gradient.
- The Wireframe edge takes seam_stroke (the same stroke it built by hand).
- Docs: which seams went from miter to round and which already were;
the white-light difference from the 2026-10-17 comparison is expected,
not measured; the 3D area rows record the change; the performance note
says its measurement predates the Classic Rotate and Revolve paths.
Pin craft-ui to c4b8405d, which adds a top edge and the canvas-side top
corner to icon-strip flyouts and saves the moved top per group. Accept
its new MoveFlyoutTop docking action, and restore the saved top when a
group returns to its place. A docking regression checks the cursors, an
upward top-edge and free-corner drag with the bottom and icon-column edge
fixed, and the top after reopening and in a saved layout.

Each 3D facet is stroked with a narrow seam of its own paint (0.05 to
0.75 pt; Revolve's is always 0.75 pt) so neighboring facets meet without
an antialiasing hairline. In Extrude & Bevel, Inflate and Rotate under a
white light, and in every face of the 3D (Classic) effects (Extrude &
Bevel, Rotate and Revolve (Classic); shaded, No Shading, gradient and
pattern alike), that seam kept the default Miter Join with its limit
of 10. Revolve's seams and the colored-light seams
were already round. A facet seen almost edge-on is a sharp sliver, and
its mitered seam reached up to ten times its half-width past the facet's
tip: thorns of up to 3.75 pt past the solid, along the tops of type seen
tilted and at every edge-on bevel facet.
#2706 (multiple lights) deliberately kept white-light seam joins as they
were, so that legacy white-light output stayed byte-identical to main
(its comment "Preserve existing white-light paints, alpha composition and
seam joins exactly", and four PNGs compared byte for byte). That kept
the thorns too. This change reverses that one part on purpose: the
paints and alpha composition stay exactly as #2706 left them; only the
join changes.
- Outputs change, the document model doesn't. Exports draw the new
joins (SVG writes stroke-linejoin="round", PDF and .ai draw round
joins), and Expand Appearance writes round seams into the document.
But nothing a document stores selects the join, and the format is
unchanged, so there is no version gate: an old file drawn now simply
has no thorns.
- Round joins. Projected facets rarely have right-angle corners (a
square seen at an angle is a parallelogram with acute corners, and an
exact 90° corner sits at a √2 limit), and round is what the seams of
colored lights and Revolve already draw. The cost: where a facet has
no neighbor (Rotate's plane, every silhouette corner) its convex
corners are drawn rounded by up to 0.375 pt instead of sharp.
Alternatives weighed and not taken: a Miter Join with a limit near √2
at every seam, the composed clip included, which would bevel slivers
but chamfer most projected corners as well; and seaming only the edges
facets share, or clipping facets to their union as solid_surface
does, which would keep every outer corner sharp but means a new
geometry pass for every 3D effect. Round is the smallest change that
matches the seams already drawn.
- A seam no longer reaches past its facet by more than half its width,
so the art's visual bounds shrink by up to 3.375 pt where a thorn
stood (10 × 0.375 less the 0.375 a round seam still reaches).
White-light output is no longer byte-identical to #2706's comparison;
docs/3d-lighting-performance.md says so.
Every seam stroke is made by lighting::seam_stroke. The colored clip in
composed_art already outlined its seam with round joins and is
unchanged. Tests: every seam of Extrude & Bevel, Extrude & Bevel (Classic, each
branch), Rotate (Classic), Inflate and Rotate, under white and colored
light, has round joins and reaches no more than half its width past its
face, at views that make a sliver; Revolve (Classic)'s seams are round
on each surface; a mitered seam fails them, and so does the legacy
white-light Inflate test, which now expects Round.
Effects apply in the order they are listed, so an effect listed after a
Transform effect applies to the art the Transform effect made, at its
own values, as an object's later effects do after the object's
Transform effect. With Scale Strokes & Effects on, a fill's or stroke's
own Transform effect scaled the effects listed after it in that fill's
or stroke's list by the mean scale: a 300% Transform turned a 5 pt
Offset Path after it into a 15 pt one, and a Drop Shadow after it took
three times its offset. With Transform Patterns or Scale Strokes &
Effects on, an SVG filter after it also had the origin of its user space
moved.
- The effects after such a Transform effect now keep their values, on
the transformed art and on each copy, on every fill and stroke a
live-effect plug-in paints the piece with, and when the copies are
counted against the effect budget.
- With Transform Objects off, the effects before it keep their values
too.
- The Transform params text, docs/target-app-parity.md and docs/gaps.md
describe the rule, and drop the note that listed an object's later
effects keeping their distances as a shortfall.
In a CID-keyed font whose CIDFont the file only names, a cshow procedure
now runs with the CIDFont as the current font, rootfont gives the
composite font, and the procedure gets each code's last byte. A show in
the CIDFont shows the character of that code, and any other string is a
rangecheck error. The current font is restored after each procedure.
A kshow procedure no longer leaves a font it sets current: the current
font is restored when the procedure completes, for every font, and a
kshow the procedure runs sees the font the procedure set.
In GBT-H and CNS2-H, whose mappings are not read, a byte that starts no
row-and-cell code is a code of its own.
docs/gaps.md dates this G9 work in a bullet of its own.
The Width menu now offers Tilt, Bearing and Rotation beside Fixed and
Pressure, each with the second width. Tilt goes from Width with the pen
lying flat to the second width upright; Bearing and Rotation go from
Width at -180 degrees to the second width at 180 degrees, as Scatter
Brush Options' modes do. A stroke drawn without that input is half way
between the two widths. brush.options takes width_mode tilt, bearing
or rotation.
With one object that Start Global Edit accepts selected with the Selection
tool, the canvas now highlights the other objects a start would take with the
current Global Edit Options, before Global Edit starts. The outlines are kept
per document revision and options, and none are shown during a drag.
Docs: docs/mcp.md (Global Edit), docs/gaps.md (G5).
- `charpath` in a CIDFont only named, over a predefined CMap, adds the
outlines of the characters its codes stand for, placed as `show` sets
them, and moves the point as `show` does. It added no outlines.
- `cshow` gives its procedure each code of such type, two bytes for a
two-byte code, with the code's width. It split two-byte codes into
single bytes.
- `glyphshow` sets the named character itself. It set the character's
UTF-8 bytes as Latin-1 letters.
- `kshow` runs its procedure between each two codes of such type, with
the two codes' values. It didn't run it. The procedure sees the font
the file set as current, and a font it sets stays current.
- A name that ends in the row-and-cell CMap `H` or `V` splits off the
CMap only when the file defines the CIDFont of that name (as a
resource or with `definefont`), or the name has a hyphen and an
installed face that covers Japanese has it. `Foo-Bold-H` stays a font
of the whole name.
- In a CMap that can't be read (`GBT-H`), each code moves the point one
em, along the line or down the column; a tab or carriage return byte
is a code of its own.
- One parser reads the names of the predefined Unicode CMaps, for EPS
and legacy `.ai` type.
- Outlines added to a path by `charpath` stop at the path's point limit.
- docs/file-format-parity.md, docs/gaps.md and docs/mcp.md describe type
in named CIDFonts over the predefined CMaps.
A linear, radial, conic or diamond gradient has a spread: Pad (the
default, as before), Repeat or Reflect, with a count of 1 to 100
(VectorCraft's own limit). Repeat and Reflect run the stops that many
times along the vector (around the turn for a conic) and keep going past
both ends, Reflect running every other run backwards, as SVG's
spreadMethod does.
The Gradient panel has a Spread menu and a Repeats field, and the
Gradient tool marks where the runs meet. paint.setFill and
paint.editGradient take `spread` and `repeats`; bad values are errors.
Presets, swatches, blends, strokes along or across a path, Outline
Stroke and Object › Expand follow the spread; Expand gives each run the
same whole number of objects, and Outline Stroke's mesh keeps the color
on each side of a sharp step between two stops at one offset.
SVG writes and reads spreadMethod: SVG import now reads a repeating or
reflecting gradient as one that repeats or reflects once, instead of
expanding its stops over the shape. CSS writes repeating gradients.
PDF writes a conic's sweep shading over one run. PDF, EPS, legacy .ai
and the .ai editing data write the other kinds with their stops
repeated across the shape: at most 256 runs and 16,384 stops (256 stops
in .ai files), and for a radial or diamond no farther than 65,536 runs
from its center, with a warning past those. PDF import now finds sharp
steps in any axial or radial shading instead of blurring them.

Review feedback: with no tolerance, pen or trackpad jitter turned a tap
into a drag and the value was no longer selected. A release within 1 pt
of the press is a tap; anything further keeps the caret.
Regression test: a_tap_with_a_pixel_of_jitter_still_selects_all_on_release.
- After a drag past either end of the range, the first arrow key now
steps back from the value shown instead of doing nothing.
- With the Selection tool, a plain double-click on a blend widget no
longer edits or isolates the artwork under it, or leaves isolation.
Ctrl/Cmd+Shift double-click still releases a guide there.
- docs/mcp.md says the lower widget shows only when the steps follow
the spine, and the G13 blend easing entry in docs/gaps.md no longer
lists on-canvas easing handles as missing.
