Every shaped segment built its own harfrust shaping plan, although a
plan depends only on the face, direction, script, language and features.
Opening a document lays out each type object once, so a document of many
short objects built thousands of identical plans.
A font face now keeps up to 32 plans, oldest dropped first, and shapes
with the one that matches. Feature ranges still come from the shape
call, so text with the same features over other ranges shares a plan.
The glyphs, bounds and baselines do not change.

Past a gutter of 1e300 a step no longer moves the baseline, so every cell of
a 100 x 100 frame was searched for all MAX_STEPS steps: over 40 s per layout.
AreaOptions::gutter has no limit, so a saved file can do this.

To find the characters that justification or Mojikumi moves, SVG export
without Fewer <tspan> Elements laid out every live type object a second
time, as point type with
Mojikumi None and default Justification options, whenever its paragraph
had Mojikumi on. New type gets Line-end Punctuation Half Width, so every
new type object was laid out twice. Mojikumi only spaces Japanese
punctuation and Japanese letters, so type without them lays out the same
either way.
- TextLayout::mojikumi_applies says whether the text or a list marker
holds a character Mojikumi spaces.
- reader_advances keeps such a paragraph's Mojikumi, and reads the glyphs
from the layout it was given when the object it would lay out is the
same; otherwise it lays the object out again as before.
The SVG is unchanged. Exporting 5,000 point type objects takes a median
of 109.4 ms instead of 171.5 ms on Windows 11.
Optical moved every pair all the way to a fixed 0.08 em ink gap, tighter
than most text faces' own stem spacing, so ordinary text was squeezed
(at 100 pt, Source Sans 3 `nn` closed from 54.7 to 46.9 pt).
Each pair now moves 0.6 of the way toward the face's reference gap (the
median ink gap of `nn`, else `HH` or `oo`; 0.08 em when it has none),
keeps at least 0.3 of it at its narrowest, and changes by at most
0.12 em tighter or 0.06 em looser. Ideographs, kana, hangul, fullwidth
and CJK punctuation forms and dashes keep the font's spacing.

Follows #5442.
- text.setGlyphAlternate keeps the default glyph as a choice when a
feature of the character's style (salt, a stylistic set) draws another
glyph for it, so the default glyph is drawn. A character that is not
laid out (overflowing text) is shaped alone in its style to decide.
gid: null reports the glyph the style draws.
- The Glyphs panel's alternates grid shows the default glyph first when
the font does not list it, so a chosen alternate can be put back.
- A test for a chosen character that starts a longer grapheme (f with a
combining acute), which is not split from its mark.
- The alternates tests in the engine hold the shared font lock while
they add fonts to the global font database.
With System Layout on or Fractional Widths off, each advance is rounded
to whole points, but a right-to-left character with manual kerning
still moved by the unrounded kerning value. The difference between the
two changed the space after the character before it in reading order.
The character now moves by the change the kerning makes to its rounded
advance, so only the space before the next character changes.
Baseline shift on an upright glyph in vertical type moved it up the column
instead of across it, at any Character Rotation, because the shift was
applied before the glyph was turned upright. The shift is now taken off
before the turn and put back after it, so an upright glyph moves across the
column by the shift as a letter lying on its side does, and still turns
about its shifted pen position.
The menu bar builds Type > Font in every frame, the first included, and
its family list waited for the scan of every installed font. When that
scan took longer than the 20 s first-frame watchdog (thousands of fonts
on a slow disk, or each file checked by antivirus), the app took the
graphics adapter for hung and started again without it, until none was
left and no window ever showed.
The menu now lists the fonts already loaded until the scan ends, then
all of them (FontDb::menu_family_list_now, installed_fonts_ready).
optical_pair_after_rtl_separate_mark_uses_base_outline sets Noto Sans
Arabic, which is not in assets/fonts. Without CRAFT_FONTS_DIR the font
database returns a fallback face, so the test checked that face instead.
The test now skips when Noto Sans Arabic is missing, as the Shippori
Mincho tests in the same file do.
With SCALED_COMPONENT_OFFSET, a component's offset now scales each axis
by the length of that axis's basis vector, as the outline loader does,
instead of going through the whole matrix. A rotated or skewed
component's caret no longer lands away from its drawn point.
UNSCALED_COMPONENT_OFFSET now turns the scaling off when both flags are
set.
A composite glyph whose components expand into glyphs with no points
could make the contour-point caret lookup read billions of glyphs. The
whole lookup now shares a budget of 65,536 glyph reads and gives no
caret when it runs out, so the caret falls back to dividing the advance.
On a path, vertical type turns an upright glyph about its pen, so its cell
runs from 0.12 em before the pen to 0.88 em after it without the font's
vertical metrics. The ligature caret, a click and the selection measured
the cell from the pen instead. They now take the cell where the glyph's
transform draws it, with its placement, baseline shift, Horizontal Scale
and Skew.
A manual kerning value on an inline graphic's character was stored and
shown but did not move the text after it. The graphic's advance now
includes the value, as a letter's does, and in right-to-left horizontal
type its art moves right by the value, so the space goes between it and
the next character in reading order. Auto and Optical kerning still apply
no font pairs to an inline graphic.
Right-to-left manual kerning was added to the glyph's offset, which
Character Rotation turns, so a rotated character with kerning moved
across the line (up at 90 degrees) instead of away from the next
character in reading order. The shift is now applied to the pen
position along the baseline, outside the rotation, and the rotation
turns the glyph about that moved pen position.
A manual kerning value on a character in right-to-left text changed the
space between it and the character before it in reading order, under
both Auto and Optical kerning. The shaped glyphs of a right-to-left
cluster now also move right by the value, so the space its advance
gains is at its left, between it and the next character in reading
order. Left-to-right text and tracking are unchanged.
Optical kerning no longer takes the left glyph's manual value off the
advance it measures, since right to left the value is in that glyph's
offset as well.
Area type made from the editing data's text document came in with one
row, one column, the 18 pt gutter and the Ascent first baseline,
whatever its frame kept. Each area frame now keeps its rows and columns,
the gutter between rows and the gutter between columns, and its first
baseline (Fixed, Cap Height, Leading or x Height) with its minimum,
scaled with the art's units. Each frame of a thread keeps its own, and a
key that is missing or can't be read leaves that option as it was. A
first baseline the frame keeps is no longer replaced by the fixed one
that matches the file's first line.
AreaOptions gets row_gutter (rowGutter, left out while unset), which
layout spaces rows by; text.areaOptions takes and reports rowGutter, a
gutter given alone sets both, and the Area Type Options dialog shows
Row Gutter.
Area type whose frame a wrap object covers sets no line and overflows.
Area type wrapped around a shape of 10,000 anchors sets its lines beside
the shape.
Baseline shift now moves a character in the line's frame, outside
Character Rotation, so a positive shift moves a character up from its
line at any rotation, and the character turns about its shifted pen
position. The Touch Type tool splits a drag into its part along the line
(kerning) and its part up from the line (baseline shift) at every
rotation; before, within about 6 degrees of a quarter turn it dropped
the cross-line part.
Characters that already combine a rotation with a baseline shift are
drawn in a new position. Their stored values do not change.
- text: glyph transform order, PositionedGlyph::pivot (the turning
point), tab leaders in the same order
- tools: Touch Type splits drags against the line's up axis and measures
rotate-handle turns about the shifted pen position
- engine: text.touchType description; dy is up from the line
- docs: mcp.md Touch Type paragraph, target-app-parity.md progress line
Character panel menu > Standard Vertical Roman Alignment, with Show East
Asian Options, is now a check item. It sets a new character attribute,
`standardVerticalRoman` (text.setFormat, text.setRangeStyle), off by
default and saved only when on. In vertical type the marked Latin
letters, digits and other characters that would lie on their side stand
upright one below the other, each in its upright cell. Spaces keep their
width and tate-chu-yoko blocks stay across the column. Horizontal type
keeps the mark and does not change. A combining mark shaped as its own
glyph turns with its letter, in Latin and CJK upright type alike.
Character Style Options labels the Character Alignment row "Character
Alignment" and gives Standard Vertical Roman Alignment its own checkbox.
Reset Panel turns the attribute off. PDF and SVG export place the glyphs
from the layout and need no change.
In typography and Illustrator, Shift+Enter inserts a soft return (forced
line break) rather than ending the paragraph. Text wraps to the next line
without applying paragraph-level spacing (space before/after, first-line
indents), list continuation lines keep their parent item without repeating
markers, and justified text does not stretch lines ending with a soft return.
- Forward active modifier keys for Enter in ui-egui shortcuts so the tool
detects Shift+Enter.
- Type tool inserts U+2028 (LINE SEPARATOR) on Shift+Enter.
- Text shaping and layout treat U+2028 as an invisible zero-advance control
character, breaking the line in point and area type.
- Paragraph spacing and list markers apply once per paragraph as intended.
Character Rotation turned a glyph's baseline shift and scaling with the glyph, and the Skew path effect slants a glyph's height away from the path's normal, so the x-height guide moved off the glyphs. Each positioned glyph now carries the transform that removes its Character Rotation (PositionedGlyph::unturned), and the guide goes through the glyph's x-height point placed without it, measured across the baseline. Snap to Glyph also takes Smart Guides being on in the tools, as View › Snap to Glyph already does in the engine.
