`insideFirst: true` (default false) draws each pen's path only after
the pen's paths that lie inside it: a letter's counter before the
letter, a part's holes before the part. Without `sortPaths` the paths
otherwise keep paint order; with it, the next path is the nearest of
those free to draw.
Touching outlines count as inside; crossing ones, and copies of one
outline, do not. Finding which paths lie inside which shares the plot's
work budget with sorting, and each case that runs out of it adds a
warning.

Window › Swatch Libraries › Gradients gains Organic Fades, a gradient
library of fifteen fades (ten linear, five radial). Each runs through
three to five unevenly spaced stops with off-center midpoints, mixes
with the Perceptual method, and thins out to transparent at the end of
a linear fade or at the edge of a radial one. The colors are computed
from VectorCraft's own OKLCH anchors.
The library also lists in the Swatches panel's library menu, in
swatch.library.list (category "gradients") and in the Gradient panel's
Presets. swatch.library.add keeps each fade's stops, opacities,
midpoints and method in RGB and CMYK documents.
The other built-in libraries are unchanged: their gradients still mix
with Classic and keep centered midpoints, and a test checks it.
- Gradient previews in the Swatch Libraries panel, the Gradient
panel's Presets menu, swatch tiles and the toolbar drew every stop
opaque. Each chip vertex now takes the sampled opacity as its alpha
(freeform points too), and a chip with any translucent vertex draws
a white and gray checkerboard under the gradient. Opaque gradients
draw as before.
- When the preferences are applied, a saved gradient preset whose name
matches a built-in preset, or an earlier saved preset, in any case,
is renamed to the first free "<name> N" (N from 2), so a saved
preset named like a new built-in fade stays listed and can be
applied and deleted.
VectorCraft could open and place HP-GL plot files but not write them,
so art for a pen plotter or a vinyl cutter had to go through another
program.
Export As, document.export and Export Selection now write HP-GL.
vectorcraft_cad::hpgl::export draws each visible path once along its
own line: a filled shape is its closed outline and a stroked path its
center line. Type is drawn as glyph outlines, a gradient mesh as its
outline, and a symbol instance as its art with its effects and the
instance's stain. Clipping masks cut the art they clip, and the art is
cut at the artboard's edges. Hidden and non-printing layers, hidden objects,
objects at 0% opacity, template layers, guides and placed images are
left out. Coordinates are plotter units (1016 to the inch, y up) from
the artboard's bottom-left corner or its center, and art more than
8,388,607 units from the origin is cut off.
Each color is a pen, in the order the plot first draws in it (up to
255), or a pen table maps each path to the pen of the nearest color.
With Use Artboards every file of the export uses the same numbering.
The pens draw in turn, each in paint order or, with sortPaths, nearest
path first. Curves are flattened to curveTolerance (0.1 pt by default).
hpglVersion "hpgl" writes IN, SP, PU and PD; "hpgl2" also writes the
palette (NP, PC) and each pen's paths as one encoded polyline (PE).
Options are checked, and Export As writes the file with the defaults.
Plots read back by the HP-GL reader give the same lines.

A new gradient kind, `diamond`, runs its stops from the center (the
start) out to a square with a corner at the end of the vector; the
aspect stretches the square across the vector into a rhombus. The
Gradient panel's Type row has a Diamond button, the Gradient tool draws
the square with the aspect handle and center ring, and a gradient
fitted to an object covers its box.
- Model and canvas: the level is |x| + |y| in the square's frame; a
square with no area (no vector, an aspect of 0, numbers out of range)
paints the last stop. The canvas draws it as pixels, out to a
stroke's miters, caps and arrowheads. Transforms keep the vector and
take the mapped size across it as the aspect.
- Commands: `paint.setFill`, `paint.editGradient` and
`paint.setGradientGeom` take `kind: "diamond"`; a negative aspect or
a focal point is an error. A conic or diamond gradient that a plug-in
returns with a focal point loses the focal point.
- Gradient tool: dragging the aspect handle of a radial or diamond
gradient whose file gave it a negative aspect now sets a positive
aspect; only a conic's negative aspect mirrors it.
- Export: PDF, SVG, EPS and legacy .ai write four linear gradients, one
for each quarter of the square, clipped to the shape (PDF as axial
shadings). PDF and SVG write an image for translucent stops, a
dithered fill or a flat square, and for the Perceptual method unless
PDF writes the stops as spot color shadings. SVG writes a diamond on
type characters as a radial gradient through the corners, and so
does CSS. A swatch library saved as CSS gets four corner layers, a
value for the `background` property (a circle when the swatch is
turned by an angle that is not a multiple of 90 degrees). The .ai
editing data holds a radial gradient through the corners. The
document exports give a warning.
- SVG export: a stroke drawn as an image, as conic wedges or as diamond
quarters now covers the miters, caps and arrowheads that reach past
its paint box.
- PDF import reads a function-based shading whose color is the same
along each square about the origin of its space as a diamond.
- Object > Expand gives nested squares or a mesh of rings.

action.batch read its true/false options with a fallback, so
{"stopOnError": "false"} kept stopping on the first error, and a
number for a string option such as label or datasetFileNaming was
dropped or turned into an empty string. The source check also ran
after the destination folder was made.
includeSubdirs, overrideOpen, overrideSave, overrideExport and
stopOnError now take only true or false, and source, folder,
destination, destinationFolder, datasetFileNaming and label take only
a string. Any other value is an error naming the key, given before the
destination folder is made or a file is opened. A null reads as a key
left out. The params text and docs/mcp.md say so.
script_pump read vectorcraft_doc::cancel only after the guard that keeps
a run waiting, so a run asleep in $.sleep went on waiting until its wake
time (up to 1,000 ms), and a run waiting at a dialog or for approval to
grow waited until someone answered. The check now runs before that
guard, after the dialog-failure check, so a canceled request ends the
run at the next slice and every document goes back.
Direct and indirect eval, Function and host evaluators parsed and compiled
their source before taking any fuel or checking the heap, so a script with a
small fuel limit could make the interpreter parse megabytes of source in a
handful of instructions. Interp::prepare_source now takes one unit of fuel for
each UTF-16 code unit and checks that the source text fits in the heap before
the source is flattened, parsed or compiled. A host evaluator's string takes
the fuel for a third of its bytes before it is encoded, and the rest after.
Limits::fuel and the maxFuel row in docs/mcp.md say so.
A new built-in add-on, Image Tools (Object › Plug-ins › Image Tools),
adds Remove Background… (`addon.image.removeBackground`). It makes the
background of the selected images transparent by lowering the alpha of
their own pixels, in one undo step, with no service or model. The
background is the most common color along the image's edges, the
average of the image's corners, or colors the user picks. Contiguous
(on by default) clears it only where it reaches in from an edge; off,
it is cleared wherever it is. Tolerance and Softness (0 to 100, 10 by
default) set how near a color must be to be cleared and the band over
which pixels fade out. Match measures that nearness as the RGB
distance or as the largest difference on one channel. It is a
VectorCraft addition.
- The image stays an image: an embedded PNG with alpha, the source's
ICC profile and resolution, and 16 bits or gray when the source is.
A linked image is embedded and keeps its Placement Options.
- When the edges hold at least as many clear pixels as pixels of their
most common color, edge mode clears nothing, so a second run leaves
the subject alone. Corner mode leaves clear corners out of the
average and clears nothing when all four are clear.
- With Match set to Each Channel, a tolerance of t / 255 × 100 clears
the colors within t 8-bit steps on every channel.
- A CMYK image, a linked image that shows its preview, an image that
would need more than the decode allowance (checked from its header)
and a result with no pixel left are refused, and the document stays
as it was. When no pixel changes, no undo step is added. The result
reports `cleared`, the pixels made fully clear.
- Picked colors are hex colors, with or without `#`, or black, white,
red, green or blue.
- The dialog opens with Preview off; with Preview on, the canvas shows
the result, and Cancel puts the image back. While the dialog
previews, the session keeps the images' decoded pixels (at most
128 MiB, 32 MiB in the web app) so each preview step does not decode
them again, and releases them when the dialog closes with OK or
Cancel. A run that is not a preview step keeps nothing.

An XML declaration at the start of XML or XMLList text was skipped up to
the next "?>" without being read. It is now checked against XML 1.0's
grammar (https://www.w3.org/TR/xml/#NT-XMLDecl): a version of "1." and
digits, then an optional encoding name and an optional standalone "yes"
or "no", in that order, with optional white space before "?>". Any other
declaration gives "SyntaxError: invalid XML declaration", and a character
XML does not allow gives "invalid character in XML text". White space
before the declaration is still accepted.
The parser now takes fuel for the length of the declaration and the
white space before it, element and attribute names, white space in open
and closing tags, and the text it searched when an attribute value, CDATA
section, comment or processing instruction is not closed, or when "]]>"
or "<" stops a text run or attribute value. A long run in any of these
used the same fuel as a short one.
Grouping for flattening joined every pair of objects whose 1 pt reach
boxes touched, transitively, so a row or grid of opaque objects next to
one see-through object became one group and was flattened with it.
Now a group holds each see-through object and every object its reach
touches. An object without transparency joins only where its reach
touches a member and it lies above that member but below the group's
topmost object, whose place the group takes, so the stacking order
stays the same. In files without transparency with Clip Complex Regions
on, art under a group within one image pixel of a member joins it too,
with the pixel size taken from the image's actual resolution. Objects in
an overlap set that includes one inside a clip group or clipping layer
keep the previous grouping.
The 1 pt antialiasing margin now goes around a group's art once instead
of once per nested group (a stroked path's plain art is a group, so it
had 2 pt).
On 3,000 stroked rectangles, 60 with a drop shadow, the Flattener Preview
counts 180 affected objects where it counted 3,000, and Flatten
Transparency with the Medium preset makes 240 flat regions and 2 images
where it made one image of the whole grid.
