A linear dimension between two clicked points, or dragged out from a
segment, always measured the straight distance between its points and
drew its line parallel to them, so two points at different heights gave
only a slanted dimension. The linear dimensions help describes aligned,
horizontal and vertical linear dimensions: after the second click,
clicking again gives an aligned one and moving the pointer gives a
horizontal or vertical one.

While a linear dimension is being placed, the pointer's position sets
whether it is aligned, horizontal or vertical. The rule is VectorCraft's
own. With the pointer beside the two points (the nearest point of the
line through them lies between them) or on that line, the dimension is
aligned. Past either point, the line through the points and the
perpendicular through that point bound a quarter on each side of the
line. The quarter that holds the direction straight up or down gives
the horizontal distance, and the quarter that holds the direction
straight left or right gives the vertical distance. A click within
reach of the second point, or of where the pointer was for the second
click, places it aligned. Points on one horizontal or vertical line
give an aligned dimension. The dimension stays linked to the anchors it
measures.
- Dimension recipes carry an orientation (aligned by default; files
without it open as before). The line runs along the axis, and each
extension line runs from its point to it.
- dimension.create and dimension.update take orientation: aligned,
horizontal or vertical, for linear dimensions only. Any other value
is an error. A new orientation keeps the line on the side of the
points it was on, and an update that changes nothing records no
undo step.
- A horizontal or vertical dimension keeps its orientation when it or
the art it measures turns, and shows 0 when its points come into line
across its axis. A line that lay outside the points stays outside
them after a turn.
- The hint bar names the two-click placement.

A constrained move keeps only the snap correction along its direction, and that correction exists only when an edge ends within a quarter cell of a gridline. When no edge on those axes is that close, the move does not snap.
A Reshape drag on an open path moved only the anchors within half the
diagonal of the path's bounding box, measured along the path. On a
zigzag, a wave or a spiral that is one or two anchors, so dragging an
end moved the end and left the rest of the path where it was (#2723).
path.reshape now stretches an open path from the grabbed point to both
ends. The end anchors stay in place. Each anchor between an end and the
grabbed point takes u² (3 - 2u) of the drag, where u is its distance
from that end along the control polygon divided by the grabbed point's
distance from that end. A handle takes the share on the tangent line of
that curve at its anchor, so the handles of a smooth anchor stay in
line with it. A handle that is long beside the span takes a share below
0 or above 1.
This changes the default for every caller that leaves radius out on an
open path. A closed path still moves the anchors within half the
diagonal of its bounding box, and a call that gives radius uses that
radius on open and closed paths.
- A negative radius is refused ("`radius` must be 0 or more"). It gave
anchors beyond the radius a share above 1.
- A drag of no length on an anchor no longer records an undo step.

Part of #6435.
Reset Preferences in the Preferences dialog now opens a question over
the dialog (`resetPreferences`). Cancel or Escape goes back to
Preferences as it was, with its edits, category and search kept. OK goes
back with every preference at its default value; OK in Preferences
applies them and Cancel there discards them, as before. `prefs.reset`
still resets at once.
Docs: docs/mcp.md, docs/target-app-parity.md.
A constrained move keeps only the snap correction along its direction: a horizontal or vertical move lands the edge on its own axis, and a 45° move lands the edge on the axis whose nonzero correction is smaller. The per-axis rule now applies to unconstrained moves only.
docs/mcp.md and docs/target-app-parity.md now state that a move in
perspective snaps an edge of the joint bounds only when it ends within
a quarter cell of a gridline (PerspectiveGrid::snap_offset), and that a
move perpendicular to the plane does not snap (perspective.move skips
snap_fix when perpendicular is true).
Two PDF export passages in docs/target-app-parity.md said a gradient
that mixes a spot color with RGB or Lab stops is always written without
the spot ink, or as an image when Perceptual. A CMYK document, or an
export that converts colors to a CMYK destination profile, writes those
stops in CMYK first, so the gradient is a DeviceN shading that keeps the
ink; an RGB destination profile keeps them in RGB. The passages now say
so, as docs/mcp.md and the paint.editGradient params text already do.
A new test checks the Classic case in an RGB document, a CMYK document,
with a CMYK destination and with an RGB destination.
Reset Preferences put Points in Units > General, and OK sent it to
prefs.set, which also set the open document's units as an undo step.
OK after Reset now resets the General preference and leaves the
document's units as they are. Choosing a General unit after Reset, in
the dialog or with ui.dialog.set, still sets the document's units.
prefs.set takes documentUnits (default true); false makes unitsGeneral
set only the preference. Docs: params text, docs/mcp.md.

object.repeat.radial, object.repeat.grid, object.repeat.mirror and
object.repeat.options, and object.pattern.make, object.pattern.edit,
object.pattern.saveCopy, pattern.options and pattern.delete, read their
params with helpers that fell back to the default for a value of the
wrong type: "instances": "8" made 8 instances whatever the text said,
"rows": "2" made 3 rows, "edit": "false" entered pattern editing mode,
and a `name` that was not a string edited the selected object's pattern.
Each such value is now an error naming the param, and the document, the
selection and the undo history stay as they were. An omitted or null
param keeps its default.
- pattern.options refuses an `overlap` that is not an object, and an
`overlap.h` other than left or right or an `overlap.v` other than top
or bottom.
- object.repeat.options refuses a `center` that is not [x, y].
- object.repeat.radial refuses a negative `radius`; it used the
automatic radius before.
- object.repeat.grid reads `rows` and `cols` as object.repeat.options
does: a fraction is cut to a whole number, within 1 to 500.
- object.repeat.options applies `brickOffset` given without `gridType`
to a brick grid, and its params text lists the key.
Docs: docs/mcp.md.
After a Scissors cut (`path.split`) the whole path stayed selected: both
pieces of an open path, or the opened path of a closed one. A Direct
Selection drag from the cut then moved every anchor, so an ellipse cut
at an anchor could not be pulled open by dragging its end.
- `path.split` selects the first anchor of the piece after the cut and
nothing else, as `path.cutAtAnchors` does: anchor 0 of an opened
closed subpath, of the new path when an open path becomes two, or of
the subpath added to a path of several subpaths.
- A Direct Selection press on anchors of a selected path that lie on top
of each other takes the selected one. It took the first in path order,
which in a path of several subpaths was the unselected end.
Docs: docs/mcp.md, docs/target-app-parity.md, the `path.split` params
text.
`text.setStyle` read `font`, `style` and `justify` with `str_param`,
`size` with `len_param` and `tracking` with `num_param`, so a value of
the wrong type was skipped: `{"size": 30, "style": ["Bold"]}` set the
size and ignored the style, and `{"font": "Inter", "size": [12]}` set
the font and ignored the size. `features` dropped an entry that was not
a string and applied the rest. `text.setRangeStyle` skipped a `font` or
`style` that was not a string, `type.ruby` skipped such a `text`,
`position` or `align`, and `text.setPathHandle` moved the out handle
for any `which` other than "in".
Each of these now returns an error that names the param, before the
command edits the document. Omitting a param or giving null keeps its
default. `size` and `leading` still take a length with a unit
("12 pt", "5 mm"), and `tracking` still takes a number written as a
string ("20").
- `text.setStyle`: `font`, `style`, `justify` (`text_param`), `size`
and `tracking` (checked reads in `typecmd.rs`), `features`.
- `text.setRangeStyle`: `font`, `style`, `features`.
- `type.ruby`: `text`, `position`, `align`.
- `text.setPathHandle`: `which` must be "in" or "out".

answer_dialog sent ui.dialog.set and then ui.dialog.confirm or
ui.dialog.cancel as two requests. A dialog another control connection
opened between them was confirmed or canceled without the fields.
ui.dialog.set takes `action: confirm | cancel`, checked before any field
is set, and confirms or cancels the dialog the fields were set in within
the same request, replying {dialog, result}. answer_dialog sends set and
action together; an app whose reply has no `dialog` key did not answer
it, and the dialog is then confirmed or canceled with its own request.
A cap inset by a bevel fitted each run of sampled edges along one curve
as a whole, while the wall next to it fitted each sampled edge by itself.
The two outlines lay up to 0.25 pt apart on an 800 pt circle, which left
a gap or an overlap between the cap and the wall.
An inset outline is now fitted one sampled edge at a time in the cap as
well, so both faces draw the same curves. Caps that are not inset keep
one cubic for each curve of the art.
Test: solid::tests::a_beveled_cap_and_its_walls_share_their_curves.
Docs: docs/three-d.md, docs/target-app-parity.md.
A 3D effect on a group built its solids from the members' paths and
paint and left out each member's opacity mask, and the mask of a group
inside the 3D group. Clipping groups, blends and symbol instances
resolved for the effect lost their masks the same way.
A member, or a group inside the 3D group, with an opacity mask now
gets a scope like one with its own opacity or blending mode, and the
mask goes on the group that holds that member's surfaces. Revolve
applies it with the member's opacity and blending mode; Extrude &
Bevel, Extrude & Bevel (Classic), Inflate and Rotate draw each solid
on its own when a mask is present and put the masked members' solids
in a group with the mask. A resolved clipping group, blend or symbol
instance keeps its mask. A disabled mask is ignored.
The progress entry said caps and the walls' cap edges are cubics without
its limits. It now lists the cases three-d.md describes: an edge of a
twisted wall that is cut into pieces, a piece of curve that does not fit
after 8 halvings, and the curves past 1,048,576 for one solid.
transparency.makeOpacityMask read `clip` and `invert` with bool_or,
transparency.setOpacityMask read `clip`, `invert`, `disabled` and
`linked` with as_bool, and the New Opacity Masks and page toggles read
`value` with bool_or, so a value of the wrong type was dropped:
"clip": "false" made a clipping mask, "invert": "yes" next to another
flag was ignored, and "value": "on" toggled the page knockout group.
They are now read with switch_or, and such a value is an error that
names the param, before anything changes. Omitting a param or giving
null keeps its default.
Extrude & Bevel (both kinds) and Rotate wrote every face as straight
segments between sample points, so Expand Appearance and the exports
gave a corner at every sample. Sampling now records the curve each
polygon edge follows, and a facet carries an outline of cubics rebuilt
from it: exact without perspective, within 0.001 pt with it, and within
the sampling tolerance for bevel insets. Caps, Rotate's face and the
wall and bevel edges that meet a cap keep curves; interior bevel edges,
edges a twist cuts and edges past 1,048,576 curves stay straight.
Inflate's faces stay polygons.

A plug-in that went on calling after a failed `vc_call` still had each
later call made on the document, although the run fails and is undone
at its end. After the run's first failed call, `vc_call` now returns
`-11` (CALL_NO_CONTEXT) and the host makes no further call; the run
still fails with the first call's reason.
object.path.offsetPath, object.path.simplify, object.path.splitIntoGrid,
object.path.cleanUp, object.pathfinder.trap and addon.contour.set read
their params with helpers that fell back to the default for a value of
the wrong type: "offset": true offset by 10 pt, "joins": 3 gave mitered
joins, "addGuides": "yes" added no guides. Each such value is now an
error naming the param, and the document and the undo history stay as
they were. An omitted or null param keeps its default, and a distance
still takes a string with a unit ("5 mm"). An unknown `joins` name is
refused as well.
Make Compound Path leaves each member's graphic style id in place. A
member copied or cut on its own took the compound's appearance but kept
that old id, so the clipboard carried an unrelated style and the pasted
path was linked to a style that did not match its look.
The copied member or piece now takes the compound's link while it has
that style's look, and no link otherwise (no style on the compound, or
a gradient pinned to the compound's bounds). It also takes the
compound's knockout setting with the rest of its transparency.
object.expand read `object`, `fill` and `stroke` with bool_or, `steps`
with f64_or and `gradient` with str_param, so a value of the wrong type
fell back to the default: "fill": "yes" expanded the fill, "steps": "16"
made 255 strips and "gradient": 3 made strips. They are now read with
switch_or, number_or and text_param, and such a value is an error that
names the param, before anything changes. Omitting a param or giving
null keeps its default.
A call whose arguments hold a file or folder key at any depth, such as an
effect's textureImage.path, is refused before the command runs; the walk
keeps its own stack. Each call also runs with automation file access
confined to no roots, so every checked read or write a command makes is
refused, whichever param carried the path.
Create Gradient Mesh, a Mesh tool click and Object > Expand of a gradient
to a mesh gave each border edge one cubic fitted between two mesh points
and picked the corners from the bounding box, so the border cut off
corners and curves: 49 pt off a five-point star, 54 pt off a notch.
- The border follows the outline of the largest subpath by length; border
points sit on it and an edge with no anchor inside is the exact piece
of its segment.
- Where no single cubic follows a run within 0.1 pt (a thousandth of the
size on a small outline), a mesh line goes through an anchor, the
sharpest corner first; at most 256 lines each way. Rectangles and
ellipses keep the rows and columns asked for.
- Smooth runs keep their end tangents; border handles are no longer made
collinear.
- To Center and To Edge highlight placement accounts for the extra lines
(for_path_shaded, also used for gradient fills).
- Non-finite points give no mesh; a degenerate outline keeps the old
bounding-box mesh.
Holes of a compound path are still left out, as before.
