Text geometry, clips, clip paints, effect art, brushes, live effects, pattern tiles and freeform
grids were capped by entry count and cleared wholesale on overflow, so a document past the cap
(e.g. more than 4,096 type objects) recomputed every entry on every frame. A FrameCache keeps
per-entry byte sizes and last-used frames, drops the least recently used entries of earlier
frames, and sweeps stale ones. Text geometry keeps its glyph outlines once instead of twice.

Decoded images were kept per Renderer at full resolution and never evicted, so the canvas,
render worker, thumbnails and panels each held their own copy (96 MB per 24 MP photo).
They now live once in a process-wide LRU store keyed by content, with optional mip levels
(RenderOptions::image_mips, off by default so exports stay identical). Thumbnail renders
now sweep their caches, and shadow/effect rasters share a 512 MiB budget and match by Arc.

Every edit of an object copied its whole appearance (its fills, strokes and effects, about
540 bytes for a basic object) into the new node, though a move leaves it as it is. Over 45
whole-selection moves of 10,000 paths, undo history grew by 589 MB; now 349 MB (41 % less), and
a nudge or a drag of the selection takes 12 ms instead of 15.
- Node::appearance is a vectorcraft_doc::Shared<Appearance>: copy-on-write. A clone shares it,
and the first change through DerefMut copies it (Arc::make_mut). Reads, writes, equality (also
against a plain Appearance) and the saved form are those of the Appearance itself, so call
sites read and change it as before. Sites that build or assign a whole appearance add .into(),
and the few that need a plain copy take (*n.appearance).clone().
- Node::transform changes the appearance only when it has gradients to transform, and pattern
paints are transformed only when there are some: a move no longer copies an appearance it
doesn't change.
The workspace suite (5,301 tests) and clippy pass with the change; the doc and engine suites
pass again after the transform guard.

The automatic rasterizer thread count was one per core up to 4. On a 10-core Apple M2 Pro, 8
workers are faster (9 are slower again), and vello_cpu draws the same pixels with any number:
- fit page, 50,000 paths: 66.7 → 56.6 ms; after a pan 66.4 → 51.2 ms
- 400 % zoom, 50,000 paths: 17.8 → 15.7 ms (back under its 16 ms budget)
- fit page, 100,000 paths: 137 → 105 ms; 400 % zoom 33.0 → 25.8 ms
Machines with 5 cores or fewer keep their count, and Preferences → Performance and
VECTORCRAFT_RENDER_THREADS still override it. pixels_do_not_depend_on_the_thread_count renders
a page of live effects and 400 overlapping translucent objects with 0, 1, 4 and 8 workers and
gets the same pixels.

A node with live geometry effects (Offset Path, Outline Stroke, Warp, Transform, Roughen…) had
them computed again on every frame: Offset Path's curve offsetting and boolean sweep for every
object, every time the canvas redrew. Rendering 2,000 paths that each have Offset Path, warm:
175 → 11.8 ms.
The renderer keeps each node's effected geometry, and each appearance item's own geometry
effects on it, keyed by the node's Arc identity like its other per-node caches. The entry keeps
the Arc alive, so a hit is exact and an edited object (a new node) gets new geometry. Only the
node draw_arc is drawing uses the cache: its path comes from the node alone, so its effects give
the same result every frame. Entries not drawn for three frames are swept like the rest.
cached_effect_geometry_draws_the_same_pixels renders a page of Offset Path, Roughen + Drop
Shadow, Warp + Outline Stroke and Transform objects (with item-level Offset Path) cold, warm,
after a pan and with a fresh renderer, and gets the same pixels each time; after an edit, the
warm renderer draws what a fresh one does. Keying the cache by node id instead of identity fails
it. The render suite (216 tests, golden images included) passes unchanged.

Six raster effects on the pixel-filter pipeline
(vectorcraft_effects::pixel::texture), under a new Effect › Texture
submenu between Sharpen and Video in the Raster Effects section:
- Craquelure (crackSpacing pt 2..100, default 15; crackDepth 0..10, 6;
crackBrightness 0..10, 9): the object on relief plaster that cracks into
plates about Crack Spacing apart (a Voronoi network over jittered points)
and along the quarter, half and three-quarter contours of its softened
tones. Depth sets how dark and wide the cracks are and how high the
plates' bevels and the tones stand (lit from the top left); Brightness
how brightly the surface is lit.
- Grain (intensity 0..100, 40; contrast 0..100, 50 = unchanged; grainType
Regular, Soft, Sprinkles, Clumped, Contrasty, Enlarged, Stippled,
Horizontal, Vertical, Speckle; default Regular): coloured 1-point grains,
smooth ones, clumps, 2-point grains, streaks along rows or columns, dark
specks; Sprinkles and Stippled use the background colour, white.
- Mosaic Tiles (tileSize pt 2..100, 12; groutWidth 1..15, 3; lightenGrout
0..10, 9): irregular tiles bevelled at their edges, with sunken grout half
a point wide per step, lightened as Lighten Grout says.
- Patchwork (squareSize pt 0..10, 4; relief 0..25, 8): squares filled with
the colour around their centres, raised to heights that follow the
highlights and shadows, a little more or less at random.
- Stained Glass (cellSize pt 2..50, 10; borderThickness 1..20, 4;
lightIntensity 0..10, 3): single-coloured panes leaded in the foreground
colour (black, half a point per step), lit from behind at the object's
centre and fading out towards its corners (PixelSpace gains `extent`).
- Texturizer (texture Brick, Burlap, Canvas, Sandstone, default Canvas;
scaling % 50..200, 100; relief 0..50, 4; lightDirection Bottom, Bottom
Left, Left, Top Left, Top, Top Right, Right, Bottom Right, default Top;
invert): the object on a surface in relief. The four surfaces are height
fields generated in code (bricks in stretcher bond, plain weaves coarse
and fine, octaves of smooth noise); no image files. Load Texture is left
out.
Every pattern lies in document space around the object's centre, so the
result is the same at any zoom or raster resolution, moves with the object
and is identical on every redraw (hash noise of cell indices); slopes are
taken in document units. Work per pixel is bounded (a 5 x 5 cell search,
four or five height samples, box blurs); parameters are clamped to their
ranges and finite-checked. The Pixelate helpers (Place, the cell search,
the softened colours) are shared, Mezzotint uses the shared smooth noise,
and the effect dialogs' dropdowns translate their labels in an "effect"
context where the plain word means something else (Soft, Horizontal and
Vertical are type settings in Japanese and Chinese).
Catalogue rows with parameter docs, outsets and reaches, menu entries,
dropdowns (Grain Type, Texture, Light Direction), translations, tests
(parameters and clamping, cracks and contours, ten distinct grains, tiles
and grout, squares in relief, leaded panes and the centre light, the
textures lit and inverted, the same at twice the resolution and when
moved, canvas, multithreaded, PDF and SVG, the command sweep with junk
parameters, the dialogs and the menu) and ROADMAP.

Adds the Video group to the raster effects, after Sharpen:
- De-Interlace…: Eliminate Odd or Even Fields, Create New Fields by
Duplication or Interpolation. The fields are the rows of the document's
raster grid (Document Raster Effects Settings › Resolution, carried to
the filters as PixelSpace::line) counted from the top of the page, so
the result is the same at any zoom and moves with the page. A line
taken out copies the line above (the one below at the top), or takes
the average of the two.
- NTSC Colors (no options, applied at once): colours a composite
television signal can't carry, with luma plus chroma past 110 % of white
or luma minus chroma below -20 % in YIQ, have their chroma cut to fit,
keeping their luma. Saturated yellow, cyan and pure red lose some
saturation; legal colours stay as they are.
Catalogue rows with parameter docs, dialog dropdowns, menu, translations,
tests (effects, canvas, command sweep junk, menu) and ROADMAP.

Four Photoshop-style raster effects on the pixel-filter pipeline
(vectorcraft_effects::pixel::pixelate), under a new Effect › Pixelate
submenu between Blur and Sharpen in the Raster Effects section:
- Color Halftone (maxRadius 4..127, default 8; channel1..channel4 screen
angles -360..360, defaults 108/162/90/45): each colour channel is
screened at its angle in square cells sized so a dot of Max. Radius
fills one; each cell's dot covers the share of the cell that is the
channel's coverage-weighted mean there (white stays white, black
black). RGB documents screen R, G, B (channels 1 to 3); CMYK documents
screen C, M, Y, K inks (channels 1 to 4), also when they are drawn ink
plane by ink plane (the K plane uses channel 4).
- Crystallize (cellSize 3..300, default 10): every pixel takes the
colour at the nearest of one jittered point per cell (exact Voronoi
over a 5 x 5 neighbourhood, pruned by distance).
- Mezzotint (type: Fine/Medium/Grainy/Coarse Dots, Short/Medium/Long
Lines, Short/Medium/Long Strokes; default Fine Dots; a dropdown in the
dialog): each channel is turned fully on or off against its own random
threshold pattern, so the object becomes pure colours.
- Pointillize (cellSize 3..300, default 5): one dot of random size per
cell at a jittered point, coloured by the softened object there and as
opaque as the object at its centre, stacked in random order over a
white canvas where the object is.
Lengths are in points (Scale Strokes & Effects scales them) and every
pattern lies in document space around the object's centre, so the
result is the same at any zoom or raster resolution, moves with the
object, and is identical on every redraw (hash noise of the pattern's
cell indices, no state). Work per pixel is bounded whatever the
parameters, which are clamped to their ranges and finite-checked; the
halftone's cell grid is capped by the raster's size and a screen finer
than 3 pixels leaves the image as it is (its average). PixelSpace gains
`channels` so the renderer tells the filters what the channels hold.
Catalogue rows with parameter docs, outsets and reaches for cropping,
menu entries, dialog labels (Max. Radius, Channel 1-4, Cell Size), the
Mezzotint Type dropdown, translations, and tests: parameters and
clamping, tone and coverage, CMYK inks, polygon crystals, pure-colour
mezzotints with ten distinct patterns, dots on a white canvas, the same
result at twice the resolution and when moved, the canvas, PDF and SVG
through the engine, the command sweep with junk parameters, the dialogs
and the menu.

Gaussian Blur and Feather drew through a filter layer whose blur works on
a coarser grid tied to the canvas: the blurred art moved by up to about
a pixel, and its steps showed, as the view moved by parts of a pixel
(scrolling, zooming about the pointer). They now blur the content's own
pixels on the CPU, as the Photoshop-style effects already do: the same
look wherever the view is, cached while only the view moves.

Effect › Blur › Radial Blur (spin/zoom, draft/good/best) and Smart Blur
(Normal mode), Effect › Sharpen › Unsharp Mask: Photoshop-style filters in
vectorcraft_effects::pixel, run by the renderer on the object's pixels in
stack order with Gaussian Blur and Feather, cached while panning; lengths in
points, bounded work per pixel. PDF, Expand Appearance and SVG export write
the effected objects as images. Dialogs with preview (method/quality
dropdowns, fields in documented order), menu entries, translations, tests.

Type and symbol instances attached to a plane keep their art and carry a projection
(Node.perspective.projection, append-only); the canvas and every export draw their outlines
through it (reshape/bake), so they are foreshortened and stay type and symbol instances. Bounds,
hit testing and transforms follow the projection. Object › Perspective › Edit Text
(perspective.editText, or double-clicking with the Perspective Selection tool) shows the type flat
where it is drawn in isolation mode; exiting isolation projects it again. Release with
Perspective keeps their look. Copies, pastes, duplicates and Selection-tool moves keep the
attachment (the art moves as dragged). Flare, spiral and polar grid draw on the active plane, and
so do the click-to-size shape dialogs (perspective.draw `at`: sizes in plane units).

The issue asked for non-destructive colour adjustments in the Effect menu
and the Appearance panel that work on vector paints, live type and
embedded images. Only the destructive Edit Colors commands existed, and
the live-effect pipeline only knew geometry and raster effects.
Effect > Color Adjustments adds six effects (adjust.*). They recolour,
in stack order, everything an object paints with: fills and strokes
(gradient stops too), type, gradient meshes, embedded images and a
group's members, each colour keeping its model. The Edit Colors walk over
an object's colours moved to vectorcraft_doc::recolor so the commands
and the live effects share it. The renderer draws adjusted art through
its object-effect path (recoloured images cached within a memory
budget), exports bake the adjusted colours (images as recoloured
copies), and Expand Appearance makes them permanent. The effect dialog
shows sliders, a channel menu and a draggable Curves graph, all previewed
live as one undo step.

PNG is written by an in-code chunk writer with the resolution in pHYs and optional Adam7
interlacing (JPEG stores the resolution in JFIF). document.export takes ppi (72/150/300/other,
wins over scale), background (transparent, white, black or a colour) and antiAlias (none, art,
type: text snapped to whole pixels); Export for Screens rows take them too (plus one top-level
antiAlias, and a row's ppi names its @Nx suffix), and so does object.rasterize. Hard edges stay
hard in every offscreen pass (groups, masks, filters), whatever the thread count.

A CMYK document that shows transparency is drawn once per ink plane
(complemented C, M, Y; complemented K as a grey) so every blend mode,
opacity, group, knockout and effect composites inks, PDF-style; the
planes' inks are shown through the working CMYK profile (cached 4-D XYZ
table). Cyan multiplied over magenta now shows C100 M100. Opacity masks
keep screen luminance; RGB colours and placed images are separated
first. RGB documents and opaque CMYK documents keep the screen-colour
path.
PDF export of CMYK documents writes its transparency groups with
/CS /DeviceCMYK (luminosity mask groups stay RGB) and puts top-level
transparency in a non-isolated page-wide group so it blends in CMYK too.
Flatten Transparency composites CMYK documents ink by ink and makes CMYK
regions. Non-separable modes no longer give NaN for greys.

[Registration] is a built-in swatch that prints 100% on every plate: Separations
Preview shows it on each process and spot plate and PDF export writes it as
/Separation /All. It can't be edited, moved, duplicated, merged or deleted;
swatch.list shows it after None and the Swatches panel applies it as a swatch.
Object > Create Trim Marks strokes the marks in Registration and marks every
artboard when nothing is selected ({style?, allArtboards?}). The preference
japaneseCropMarks (General) switches to Japanese marks: double lines at the
trim and bleed edges plus centre marks. Effect > Crop Marks (cropMarks) is a
live effect whose marks follow the object; rendering, SVG/PDF export and
Expand Appearance draw them. The mark geometry lives in doc::marks.

With type selected, stroke.set (without an item) gives every run the
weight, cap, join, miter limit and dashes instead of adding an object
stroke; while the Type tool edits text, the Stroke panel styles the
selected characters through text.setRangeStyle `strokeOptions`, and the
panel reads the first run (or the selection's style).
CharStyle gains stroke_cap, stroke_join, stroke_miter_limit and
stroke_dash (defaulted, skipped when default). Character strokes and
object strokes on type now draw through the shared stroke geometry on
the canvas, in PDF and in SVG (live text writes cap/join/miter/dash and
tspans reset what the first run sets; object strokes are drawn on the
glyph outlines), so every stroke option, opacity and blend applies.
Outlines, the Eyedropper and graphic styles keep the options.

A group's or layer's own fills and strokes paint every member's geometry, below or above the
members as the new contents slot (Appearance.contents_index) says; its geometry effects reshape
the members as one piece and its raster effects apply to the composite (one combined shadow),
respecting knockout groups. Type's own fills and strokes paint under or over its characters.
Render, SVG/PDF (via bake) and Expand Appearance evaluate them alike.
Commands: appearance.* / effect.* take target: "object"|"contents" and layer ids;
appearance.moveItem moves the Contents slot (from: "contents") or an item across it
(contents); appearance.targetContents selects a group's members. Graphic styles applied to a
group now style the group itself. The Appearance panel shows Contents/Characters rows that
drag, and double-click to target the members or edit the characters' paint.

layer.clippingMask.toggle {id?} -> {clip}: the top object of the current
layer (or of the one selected group, or of `id`) becomes the clipping path,
unpainted and moved to the bottom so art added later is clipped too; pressing
the button again releases the mask and leaves the path unpainted. One undo
step. The Layers panel button runs it and underlines clipping-path names.
Model: NodeKind::Layer.clip (skipped when false). Clipped layers render, hit
test, bound, and export to SVG and PDF like clip groups (Node::clips /
set_clips); the clip-path helpers are shared with Make/Release Clipping Mask.

On screen, a group (or object) with opacity, a blend mode, an opacity mask or
knockout whose content blends is drawn offscreen over a copy of its backdrop
and mixed back in by its opacity, mask and clip (a group blend mode then
applies to the backdrop-free result, as PDF defines it). Isolate Blending keeps
the content starting from transparency. Clip groups no longer isolate their
children (blending content is clipped per drawing), and non-isolated knockout
groups composite their elements against the art below the group. Groups
without blending inside still render as plain layers.
In PDF, such groups are written as non-isolated transparency groups (a
constant-alpha soft mask instead of the writer's isolated opacity group),
knockout groups included.

Geometry effects reach objects that aren't paths through their outlines (vectorcraft_effects::
reshape: glyph outlines, evaluated live art, the symbol's art, an image clipped by its reshaped
frame), applied to the whole art as one piece; the renderer caches that art per object and
paints raster effects around it in the same filter layers paths use (shared Renderer::raster_fx,
also used per fill/stroke). Exports bake the reshaped art; SVG writes per-item filters; PDF
warns about raster effects on strokes as well as fills and objects.

Outline Stroke (and the stroke part of Expand) now builds each stroke from the
shared canvas geometry: dash shapes, arrowheads, width profiles and inside/outside
alignment, united into one clean path (pathops::stroke_region). Every stroke item
is outlined in paint order (runs of fills stay on copies of the path), stroke
opacity, blend mode and effects move to the new fill, and brushed strokes become
their brush art. The live Effect > Path > Outline Stroke outlines the stroke it
sits on (on a fill or the object: the top stroke) with that stroke's cap, join,
dashes, alignment, profile, arrowheads and weight: GeomContext now carries the
stroke and the fill rule, built per item by the renderer, export baking and
Expand Appearance.
