Three geometry fixtures used unembedded Helvetica, so the reader fell
back to Source Sans 3 widths where Helvetica is not installed (CI) and
fitted the line length instead of placing glyphs exactly; the following
"C" then landed about 3 pt off its untagged comparison. Embed the
bundled Source Sans 3 with matching explicit widths. Every assertion and
the 0.05 pt tolerance are unchanged.
An image in a Separation color space opened as an RGB image: its spot ink
was lost (no plate in Separations Preview), and Fill and Recolor Artwork
didn't reach its color.
It now opens as a grayscale image of its tints (white where it lays no
ink, black at 100 %, its Decode array applied; 1 to 16 bits a sample, or
one gray channel from its JPEG, CCITT, JBIG2 or JPEG 2000 decoder),
colorized by its ink at 100 %: the spot swatch, a process plate's CMYK
color, or Registration. Its mask becomes its opacity mask, as a CMYK
image's does. The ink is found by the image's color space among those the
file defines, once per image. The ink None, an ink whose color can't be
told, images inside an alpha soft mask, inline images and DeviceN images
open as before; samples that can't be read open in RGB with a warning, and
the ink gets no swatch.

The warning #6326 added listed the families `set_text` met while the
page ran. An Illustrator EPS can be rebuilt from its editing copy,
whose type may be in other fonts than the page's, and `stringwidth` and
`charpath` reach `set_text` without adding any type. The families are
now taken from the text objects of the document the import gives (its
layers and its symbols), once each, in the order the type comes,
whichever path built it.
Diff took the Image Trace flag of the old version for both sides when it
read each version's first member. Both versions have the same extras
there (same_but_members), so the result was right, but each side now
reads its own node.
The doc of Renderer's three_d_bounds now says what adds an entry, when
entries are swept, and the bound that follows: about twice the live 3D
art plus 1024 entries.
A mark glyph's vertical translation started a new draw_glyphs batch, so
krilla received the cluster's source range again and mapped its
characters twice. Copying or searching the exported PDF then found
doubled letters for Arabic harakat in any font, and for every dotted
letter in fonts that draw dots as zero-advance mark glyphs (Noto Sans,
Naskh and Kufi Arabic).
Keep compatible glyphs on the same layout line in one batch and carry
their relative vertical placement as per-glyph y_offset; horizontal
placement is unchanged (next_x - x advances). Font, size, linear
transform, line/column, paint run, list marker and hyphen boundaries
still split batches. Krilla keeps owning cluster mappings and
ActualText. No importer change.
Regressions decode the content stream and ToUnicode maps: one batch per
layout line, no duplicated cluster assignment, one ActualText per
multi-glyph cluster, contours within 0.05 pt of outline export; mixed
scripts, vertical columns, path rotations and PDF/X variants covered.
The reader round-trip stays an ignored test until the importer consumes
ActualText (#6165).
Addresses #6309.
ECMA-357 sends a single attribute given to [[Insert]] through [[Replace]], which makes a text node. A list holding an attribute went into the children as the attribute itself, changed its parent and stayed on its old owner. Each attribute now goes in as a new text node with its value, and it stays on its owner. A list assigned such a value holds the new text nodes, and an attribute does not count against the depth limit.
An embedded expression used as a tag or attribute name must now be one XML
name, and one used as a run of attributes must hold only name="value"
attributes separated by white space. Anything else throws SyntaxError, so a
script string cannot add an attribute, close the tag or add a child.
{name}={value} in a tag now reads as a computed attribute name, as in the
example in ECMA-357 section 11.1.4.
Editable PDF import derived characters from glyph Unicode/CID mappings
even when the enclosing marked-content sequence supplied /ActualText.
A span that paints "xy" but says "AB", followed by "C", imported "xyC".
Track the outermost replacement owner per span (absent, explicitly
empty, consumed), decode it with the existing PDF text-string decoder,
emit it once at the first placeable glyph, and let the remaining glyphs
of the span advance the pen without phantom character slots or
inferred spaces. Authored stretches keep their logical order while
adjacent ordinary text still goes through visual-to-logical
reconstruction. Glyph identity still drives font matching. Depth and
size are bounded; oversized or unbalanced spans fall back to glyph
mappings with a warning.
Outlines mode and PDF export are unchanged. Parity docs updated,
scores unchanged.
Fixes#6165.
Replacing a child with a list, inserting a list, and assigning or
replacing by name now check the depth and take all fuel and heap before
the first change. A limit no longer leaves the old child removed, part
of a list inserted or one of several matches gone.
appendChild and assignment past the end of a list remove their empty
placeholder when the assignment stops. A list that takes an earlier
sibling at an index keeps that node in its slot.
Type set in a family that isn't available keeps its name and shows in
the fallback font, as in PDF import, but EPS import said nothing. It
now notes each such family once, in the order its type comes (at most
64), and ends with PDF import's warning: "fonts that aren't available
show in the fallback font until they are: <families>".
Tests that set type in fonts the test machine may lack (Helvetica,
Ryumin, made-up names) check the program's warnings without that note,
since which fonts are installed depends on the machine.

The XML parser now throws SyntaxError when markup binds the xml or xmlns prefix or either fixed URI against the Namespaces in XML rules. addNamespace, setName, setLocalName and setNamespace throw TypeError for the same bindings and leave the node unchanged.
A new element or attribute cannot be in the xmlns namespace, and an attribute in no namespace cannot be named xmlns. The xmlns URI cannot be the default XML namespace. These assignments throw TypeError.
insertChild, prependChild, replace and list assignment take their heap
and fuel before moving a node out of its old parent. Replace past the
last child charges before the push, so a child is never left without
its parent link. Deleting a child or attribute by name, assigning an
attribute or assigning text to an element take the fuel for the whole
step before emptying the node. normalize removes the next text node
before it stores the joined text.
With `Options::e4x` set, vectorcraft-js runs ECMA-357 (2nd edition):
XML and XMLList literals with embedded expressions, the `..`, `.@`,
`.*`, `.()` and `::` selectors, assignment and `delete` on selected
nodes, `for each`, `default xml namespace`, and the four objects with
their methods and settings. The option is off by default, and without
it the syntax and globals do not exist.
Parsing, serializing, comparing and copying trees use no native stack,
and each takes fuel and counts against the heap limit. Inserting a node
into itself or its descendants throws a TypeError before the tree
changes. A literal or XML string nested past `Options::max_depth` gives
a SyntaxError, and a tree built past that depth stops at the heap limit.
`XML.prototype.xpath` is not provided.
A PDF image mask (`/ImageMask true`) painted in a solid color opened as an
RGB image with the color in its pixels: Fill and Recolor Artwork didn't
reach the color, a spot color lost its ink, and the same mask painted again
in another color took the first one, because the painted image was cached
by the mask alone, and so did an uncolored pattern whose cell draws a mask.
It now opens as a grayscale image of what it paints, colorized by that
color, as the .ai reader opens a 1-bit image mask (#5790). A spot color
keeps its swatch and tint. The page's walk counts paths, not images, so the
ink is found from the color space. Readings of a pattern cell are told
apart by colorized images' colors too. Inside an alpha soft mask, or
painted with a pattern, a mask opens as before.

copyFrom only writes paints enabled for pickup and apply, and paint, Transparency and the Eyedropper record an undo step only when the override changes.
