1-bit TIFFs compressed with CCITT Group 3 did not open, place or
relink: the image decoder reads Group 4 only and refuses Compression 2
(modified Huffman) and Compression 3 (ITU-T T.4).
They are now decoded with hayro-ccitt, the CCITT decoder that EPS
import uses. Compression 2 rows start at a byte and have no EOL codes.
Compression 3 rows follow an EOL code and are one-dimensional, or, with
T4Options bit 0, one- or two-dimensional as each row's tag bit says.
Fill bits, FillOrder 2, either PhotometricInterpretation, strips and
tiles are read.
A file whose pixels would take more than the decoding allowance as
RGBA is refused as too large to draw. A strip or tile whose data ends
before its last row is refused as damaged, and so is a tile larger
than the allowance. The strips and tiles together are read from at
most as many bytes as the file holds.
Part of #1466.

A Shaper Group keeps its original shapes as a transparent first child.
Clicks skip them outside Construction mode, but a marquee did not: one
drawn over the outline of an original shape whose face the group had
erased selected the group, where nothing is shown. Group Selection's E
marquee selected an original shape that lay inside it, and Direct
Selection's marquee and clicks selected the anchor points of the
original shapes.
The marquee now skips a Shaper Group's original shapes with the same
check clicks use, which moves into shaper_hides, and Direct Selection's
walk over the art it can pick skips them too. In Construction mode, with
the original shapes isolated, the marquee still selects them and Direct
Selection still selects their anchor points.

Optical Margin Alignment was stored and set per text object, so the
frames of one thread could differ. Turning it on in the first frame of
a thread left the lines in the other frames flush with their margins.
Type › Optical Margin Alignment and type.opticalMarginAlignment now set
every frame of a selected frame's thread, in one undo step, and the
reply's ids list them all. After any edit to a thread, its frames take
the setting of the frame that the edit turned on or off, else the
first frame's. Threading frames gives the thread its first frame's
setting, and frames taken out of a thread keep it. A file whose frames
of one thread differ opens with the first frame's setting in all of
them. This holds for native files and for documents restored from the
editing copy that an EPS, SVG, PDF or .ai file carries.
Threading text from an out port into existing area type
(text.thread.add with to) now flows the story into that frame at once.
Before, the story reached it only at the next edit of one of the
thread's frames.

A .vectorcraft file's type opened with the character and paragraph
values it held. With a size of 0, the characters were not drawn. With
a size, leading, horizontal scale, left indent or space before of
1.797e308, point type's bounds were infinite or over 1e308 wide or
high, and moving or scaling it failed with "result would exceed the
canvas".
These values are now read into range when a file opens, in the type of
the layers, symbols, graph designs, patterns and the pattern definition
that Cancel puts back in pattern editing mode, and in character and
paragraph styles. A size, horizontal scale or vertical scale of 0 or
less becomes 12 pt or 100%, and a negative leading becomes Auto. A
size, leading or scale past 4,000,000 (MAX_COORD) becomes 4,000,000,
and a baseline shift, indent or space before or after past 4,000,000
either way becomes 4,000,000 or -4,000,000. A tab stop is kept to the
0 to 100,000 pt that text.tabs.set takes. A leading of 0, which legacy
.ai import stores, and the sizes, scales and indents within these
limits that SVG, PDF and .ai import keep outside the panels' ranges
open as saved.
Docs: docs/mcp.md (Paragraph attributes per paragraph).
document.setup accepts a superscript and subscript size of 1 to 500%
and a position of -500 to 500%, and a small caps size of 1 to 200%.
text.setFormat copies these proportions into the characters it
formats. A .vectorcraft file's characters, character styles and graph
label styles opened with the proportions they held. With a superscript
size of 0, the superscript characters were not drawn, and with a
superscript or small caps size of 1.797e308, moving the type failed
with "result would exceed the canvas".
These proportions are now read as the nearer end of each range when a
file opens: in the type of the layers, symbols, graph designs, patterns
and the pattern definition that Cancel puts back in pattern editing
mode, in graph label styles and in character styles. Proportions in
range and the other character attributes open as saved.
Docs: docs/mcp.md (Small Caps, Superscript and Subscript).
The task bar offers more next steps for each kind of selection:
- an open path: Join (closes it) and Edit Path (the Direct Selection
tool); a closed path: Edit Path;
- a compound path: Edit Path and Release Compound Path;
- a clipping group: Edit Clipping Path and Release Clipping Mask
instead of Ungroup and Isolate;
- an image selected with vector art: Make Clipping Mask instead of Unite;
- point or area type: Convert To Area Type / Convert To Point Type
beside Create Outlines.
Buttons may now carry command parameters. "Edit Path" is translated in
every catalog; the other labels reuse the menu's. cargo xtask ci passes
all 9 steps.

Add opaque RGB light color and up to ten independently adjustable lights to
Revolve, Extrude & Bevel, Inflate and Rotate. Keep light selection, Add/Delete,
selected-light gizmos and preview transactions on the existing command path.
Preserve legacy white-light Inflate polygons, paint composition and seam joins,
including the 0.05 seam minimum. Use shared smooth normals for colored Inflate,
and batch solid-fill RGB channel paths behind one surface clip. Keep source
paths editable and SVG/PDF output vector artwork.
Rebase onto main f7de3d6a, retaining both sides of progress docs and all 22
catalogs. Shade freeform points once through the shared paint mapper. Document
release measurements and a reproducible CLI fixture, including the remaining
source-gradient cost and the one-light timing tradeoff.
Validation: full cargo xtask ci passed all 10 steps; 7,978 tests passed, zero
failed and 11 ignored. Four legacy white-light PNGs match unchanged main byte
for byte. Three paired release bench/perf repetitions completed without busy
warnings; all six standard perf runs passed every budget. Two-light solid
Inflate improved from 136.2 to 96.8 ms/frame at 1200x1200, default eight threads.
- Prefer the anchor over a short handle within tolerance, like hit_handle.
- Pick the nearest eligible spine point and handle.
- Constrain Shift handle drags to 45-degree steps round the anchor.
- Hide spine handles with handles_multiple off, in overlays and picking.
Artboard Options showed Name, Width and Height only: the generic form
hides x and y, which in the shape dialogs are the click position. The
artboard's position could be dragged but not typed.
The dialog now draws its own rows after the form's, in the same grid:
the reference point locator the Transform panel, the Control bar and
Properties share, then X and Y. They show where the reference point
lies, counted from the ruler origin (#1212), as the Transform panel and
the Control bar show an artboard's position. A typed X or Y moves the
artboard so that its reference point lands there, and a new Width or
Height keeps the reference point in place. The fields still hold the
top-left corner in document points, so OK runs artboard.setProps as
before, in one undo step. The shape dialogs keep their x and y hidden.
form::grid_then lets a dialog add rows to the generic grid.
The Paragraph panel menu's Roman Hanging Punctuation was a disabled stub.
It is now a per-paragraph attribute: in a left-to-right paragraph of point
or area type with it on, the punctuation Optical Margin Alignment hangs
(quotation marks, hyphens, full stops and commas wholly; asterisks,
tildes, ellipses, en and em dashes, colons and semicolons by half) hangs
outside the margin when it starts or ends a line, on the same sides
(left-aligned lines at their left, right-aligned at their right, centered
and justified at both); letters don't hang. With Optical Margin Alignment
on as well, letters hang too. East Asian punctuation keeps hanging only
through burasagari. The layout shares Optical Margin Alignment's hanging
code, given the share of each glyph that hangs.
text.setFormat takes romanHangingPunctuation; it is off by default, saved
only when on, carried by paragraph styles (New and Redefine capture it)
and turned off by Reset Panel. The panel menu item is a checkbox enabled
with type selected.

Closes#2756.
