With logoColors named, Flat Logo measured how flat the image is against
the named colors. A solid pixel counts as flat only within 22 (RGB
distance) of one of those colors or white. Flat art whose named colors
were 20 levels off in every channel was refused as not flat, and the
refusal score of a gradient changed with the names.
The check now uses the image's own colors, found the same way as when
no colors are named. It looks for as many colors as are named, with
white, or as the Colors setting gives, whichever is more. How far the named colors are
from the image's colors no longer changes whether the image is refused.
This changes one existing behavior: an image with large areas of a
color that was not named used to be refused, and it is now traced in
the named colors.

When a blend starts a key's path elsewhere (an open path clicked at its
last anchor, a closed path turned to another start or reversed to match
the other key's winding), the steps now read that key's width profile,
pen pressure, tilt, bearing and rotation along the turned path, and a
reversed open path's arrowheads swap ends. A width profile's sides swap
when its path is reversed, a closed path's samples move past the new
start keeping the step at the old one, and a split width span is sampled
so its curve keeps its shape. A key whose subpaths turned differently
keeps its stroke as it is.
Width profiles in the steps also keep their discontinuous points instead
of only the width before them, and are sampled between their points so
each key's curve keeps its shape where the other key adds points; keys
whose points sit at the same positions are not sampled, so a preset on
both keys stays that preset. A sample of one key that lies within a
millionth of the other key's step no longer hides that step.
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.
Under automation read roots, a reply's base64 `thumbnail` (a library
item's PNG in `library.get`, a page's PNG in `document.pdfInfo`) was
searched for hidden library paths like any other text, so a short path
that happened to occur in the encoded bytes was rewritten and the image
broke. `thumbnail` now joins `dataBase64`, `pngBase64` and
`thumbnailBase64` as encoded data that is left unchanged; text under it
that is not base64 is still searched.
With Size 0, Roughen moved no point but still replaced each segment
with its Detail's points joined by straight lines (Corner) or by a
smoothed curve through them (Smooth), so a curved path lost its shape.
At Size 0 each segment is now split at the Detail spacing into pieces
of equal length on the segment itself, with `pathtools::insert_at`: a
straight segment gets corner points without handles, and a curve gets
smooth points whose handles follow it. The path keeps its outline with
Smooth or Corner points alike. The params text of `distort.roughen`
describes size 0.
`insert_at` now counts the anchors added before each returned mark in
one pass. It counted them again for every split segment, which took
quadratic time on a path with many split segments. Its results are
unchanged.
Existing documents with a Roughen of Size 0 on a curved path, or with
Smooth points, draw differently.
This is VectorCraft's own rule. What Roughen does is described in

Under automation read roots, `ui.inspect` kept a folder preference whose
stored value was readable even when the trimmed path the app uses was
not: ` /outside/fonts` reads as a name in the working folder, while the
app uses `/outside/fonts`. A folder preference now stays only when both
forms are readable. A reply string is decoded for path matching only when
it holds a `%XX` escape, so a string such as `width="100%"` is no longer
decoded and thrown away. The library list line in the progress doc now
states when a hidden library's `loaded/<file name>` id moves.
docs/file-format-parity.md held 36 copies of the paragraph on the
editing copy of a file. #6202 and #6249 each added a combined copy
without removing the copies it replaced, so the count went from 34 to
35 and then to 36. The section now holds one copy: #6249's combined
copy, with the Align to Path distance clause that seven of the other
copies carry from #6247. Every other clause of the removed copies is in
the kept one, word for word or in the newer, longer form another copy
wrote. The older Align to Path clause, with its measurements for one
font at 24 pt, is removed because #6247's wording replaces it. The
paragraph now starts with a capital letter.
The summary table also repeated its "Formats opened or placed" and
"Formats saved (Save As)" rows. The older row of each is removed: the
one that still lists HEIC/HEIF as missing, and the one that lists fewer
contents of the editing copy that `.ai` saves write.
A Recent Colors chip in the Color or Swatches panel now starts a paint
drag. Dropped on the Swatches panel's list it becomes a swatch of its
color, in its color model, through swatch.new as one undo step: on a
color group or one of its swatches it joins that group, elsewhere it
joins the ungrouped swatches. A click on a chip still paints the
selected art, and a drag does not.
A paint Alt-dropped on Registration now becomes a new swatch instead of
ending in a "can't be edited" error from swatch.edit.
The new General preference Show Bounding Box While Moving and Drawing
(`boundingBoxWhileMovingAndDrawing`, off by default) keeps the bounding
box and its handles visible during two kinds of drag, with View › Show
Bounding Box on. While a drag moves the selection (a Selection tool
move, an Alt-drag copy, or a shape tool's move by the center point),
the box is drawn where the drag has moved the selection. The box is
measured once when the drag starts and offset by each step's move.
While the Rectangle, Rounded Rectangle, Ellipse, Polygon and Star tools
draw a shape, the box is drawn around the shape. A rotation and a
widget drag still hide the box until the release. The Line Segment
tool, the Pen, the Pencil and the Paintbrush draw no box.
With the preference off, the box hides during a move (#737, for #712)
and while a shape is drawn (#5839), as before. A Selection tool move
with Real-time Drawing off still moves the box with the pointer, and a
shape tool's move by the center point hides it in both modes.
With Real-time Drawing off, the box of a shape being drawn is measured
from the pending preview, in the color of the layer the shape goes on.
A shape being drawn shows no box until a preview step has succeeded,
so a failed preview does not show the box of the selection from before
the drag. The preference's label has a row in every catalog.
Session::deferred_move() is replaced by Session::move_drag_box(), which
returns the moved box, and Session::deferred_transform_box() now also
returns the layer color of the box.

A blend between two strokes drawn with a pressure-sensitive brush gave
every step the pen recording of the nearer key, so the brush jumped at
the middle step. The steps now interpolate the pressure, tilt, bearing
and rotation at every position either key has a sample. A key without a
recording counts as half pressure, half tilt and 0 degrees, as brushes
read it. Angles turn the shorter way round, and steps and whole turns in
a recording stay in the steps. Different brushes still switch halfway.
