dotCooCoo 24d4777d1a Color: freeform gradients keep CMYK inks when expanded, meshed or edited
Object > Expand and Object > Create Gradient Mesh mixed a freeform
gradient's points in display RGB and turned the result back into the
points' model with the profile-free formula. CMYK inks changed: points
of C50 M20 Y0 K10 gave mesh points of C45 M24 Y0 K22. RGB points were
stored as display sRGB, so with a working RGB space other than sRGB
the mesh showed other colors. Points colored along CMYK stops, a point
paint.freeform.splitLine added between CMYK points and a point
paint.freeform.addPoint added without a color came out as RGB.

Points that share a color model now mix in it: the C, M, Y and K
values mix as inks, and Gray, RGB and Lab components mix as they are.
Points in different models still mix in display RGB. Object > Expand
and Object > Create Gradient Mesh store the result in the working RGB
space, and in a CMYK document they store it as CMYK through the color
settings, as paint.setFill stores an RGB color. Freeform::recolor and
split_line mix with the new Color::lerp_keep_model, which
vectorcraft_doc::blend::lerp_color now calls.

dotCooCoo 62fd793603 Expand: pattern fills expand into their tiles clipped by the shape
Object > Expand with Fill expanded gradient fills only. A pattern fill
stayed a live pattern, and object.expand.info did not report it, so the
dialog's Fill option was disabled for it. In the reference app, Expand
with Fill turns a pattern fill into the pattern's tiles, and the shape
becomes their clipping mask.

The Fill step now turns each visible pattern fill of a path or compound
path into a clip group shaped like the object, holding the tiles the
pattern lays over the object's box with fresh ids. The group isolates
the tiles' blending and takes the fill's opacity, blend mode and other
effects. Geometry effects of the fill or the object, such as Offset
Path, shape the group's outline and the box the tiles cover. A path in
the tile art with a random Transform effect is baked with its own id
first, and a path with a brush that varies at random (calligraphic or
scatter with Random variation, or bristle) is baked where the pattern
defines it first, so every tile matches the canvas. The object's other
fills and strokes stay on copies of it in paint order, and Expand stays
one undo step. Type with a pattern fill expands the same way once
Object outlines it, and object.expand.info reports pattern fills under
fill. It also reports gradient fills under a new gradient key, and the
dialog enables Expand Gradient To only when the selection has one. A
pattern fill stays as it is when it lays no tiles over the box, when a
group or type in its art has a random Transform effect, when the
pattern is scaled, rotated, reflected, stretched or sheared and its art
holds a symbol instance, and when the pattern is rotated, reflected,
stretched or sheared, or scaled while its art has geometry effects, and
its art has raster or 3D effects, or a geometry effect on a group or
type.

PatternDef gains instances_in_with, which places the tiles with a given
Scaling. Expand has stroke weights, effect distances and the tiles' own
pattern paints scale with the pattern's transform. When the pattern is
rotated, reflected, stretched or sheared, or scaled while its art has
geometry effects such as Roughen, the strokes and geometry effects of
the tiles' paths become filled art first (bake_appearance, and Outline
Stroke's conversion for brushed strokes), and their live shapes become
plain paths, in their opacity masks too. Tiles place their opacity
masks with them, unlinked ones included (place_art), which also fixes
unlinked masks in pattern tiles in PDF, EPS, EMF and WMF export and in
Distort Pattern Fills.

Faults in the shared code are fixed for every caller. assemble
dropped the effects of a sole part, so Expand lost a lone gradient
fill's own effects and Outline Stroke lost those of a stroke with a
gradient along or across it. Outline Stroke also dropped a brushed
stroke's raster effects from its brush art. Expand replaced an object
whose gradient fill could not be expanded with a plain copy; it now
leaves it as it was. Expand left the geometry effects of a gradient
fill, and with Object off those of the object, on the expanded art,
where they reshaped every strip; they now shape the clip group's
outline, and the gradient fits it, as for pattern fills.
bake_appearance dropped a stroke's raster effects from its filled
outline and filled the outline of a stroke with a gradient along or
across it with a gradient across the outline's box; it now keeps the
effects and makes the gradient meshes clipped to the outline, as
Outline Stroke does. Envelope Options > Distort Appearance uses it too.
PatternDef::offsets_covering overflowed on a region too large to count
in integers, as for a pattern scaled by 1e-20; it now gives no offsets.

bflatasticandClaude Opus 5.5 7fb07bb3db M14.4: as_chunks for the pixel loops main gained since the no-panics branch
Same treatment as the branch's `as_chunks` commit (Rust 1.99's
`chunks_exact_to_as_chunks` lint) for the flattener's coverage pass, the
CMYK ink compositor, the Flattener Preview highlight and four test helpers.

bflatasticandClaude Opus 5.5 705976fd96 M3.84: Object > Expand dialog; gradient fills expand to a mesh or N objects
Object > Expand… opens a purpose-built dialog (Object, Fill and Stroke
checkboxes, disabled when the selection has nothing for them; Expand
Gradient To: Gradient Mesh or Specify N Objects, default 255). Every
option now does something:
- Object: type to outlines, live shapes to paths, effects baked.
- Stroke: strokes outlined into filled paths.
- Fill: linear/radial gradient fills become N solid rectangles or
  concentric ellipses, or a gradient mesh with lines where the colour
  changes, inside a clip group shaped like the object; freeform
  gradients become a mesh shaped like the object. Colours keep their
  stops' colour model. With Fill off gradient fills stay live.
object.expand {} defaults match the dialog (stroke now defaults on);
new query object.expand.info and UI command ui.expandDialog.
Create Gradient Mesh on a gradient-filled object takes the colours the
gradient paints at each point (GradientMesh::for_path_with, from_grid,
highlight).
