hayro (0.7.2 and 0.8.0 alike) inflates Flate and LZW data with no ceiling, so a few megabytes
of zeros ask for gigabytes, and applies a predictor before checking its parameters: Columns 0
divides by zero (a panic, an abort on the web), a huge Columns allocates a row that large (an
abort everywhere). Both happen inside the reader, before any of our limits.
A file is refused ("a stream in it would decode to more than 256 MB, or its decode parameters
can't be applied") when a stream's decode parameters ask for a predictor the reader can't apply,
or when it decodes past 256 MB through Flate, LZW, run-length and the ASCII encodings before
them, decoded here with a ceiling (only streams large enough to get there are decoded). Every
object's stream is looked at once the file is open (decrypted, references followed), with the
inline images of anything that can be content; object and cross-reference streams, which the
reader decodes while it opens the file, are looked at first in the file's text.
A scatter brush whose art is an instance of a symbol stroked with that brush, or any brush whose
art is painted with a pattern whose tile is stroked with it, drew itself without end: a stack
overflow in a hand-written native file. Brush pieces already strip the brushes of their own
strokes; now what they draw by name that would draw a brushed stroke (a symbol instance, or a
pattern paint, also through the symbols and patterns those use) is left out too, in one place
(`stroke_pieces`, which every renderer and exporter calls with the document).
Probed the rest of item 2 of the depth follow-up with hand-written hostile inputs, kept as tests:
graph designs of deep art and of a symbol holding itself, Affinity groups nested to and past
both of its reader's caps, DXF blocks inserting themselves, EMF/WMF saving states without end,
and plug-in manifests and output nested 30,000 to 100,000 deep. None of them overflowed.
hayro-syntax 0.8.0 reads arrays and dictionaries 64 deep and no deeper wherever they are (the
file's text, object streams, the content of pages, forms, patterns, glyphs and masks), walks the
page tree without recursion and follows a chain of object streams once: what 0.7.2 overflowed
the stack on. hayro-interpret 0.8.0 comes with it (a new device interface: the importer's device
takes it as before). Our raw pre-scan of the file's text and page content goes: the reader's own
cap covers more, and the scan miscounted the bytes of unfiltered binary streams.
What 0.8.0 still builds by recursion with no cap is refused when the file opens: functions and
colour spaces built on themselves or on one another more than 16 deep, and calculator functions
whose procedures nest more than 64 deep. The import runs on a 16 MB thread, as the SVG importer
does.
hayro-syntax 0.8 turns on flate2's zlib-rs backend, which the whole app then deflates with: a
compressed native file is the same gzip stream as before (header and data), but its deflate
blocks now depend on how the data is fed, so the streaming test checks the header and the
unpacked data instead of the bytes.
The rollback undid the batch's interaction, which holds the art, the selection
and panel state only: a Save As step's new file, format and saved state stayed,
and an Undo step (which ends the interaction) left the art and the history
undone. The batch now keeps the documents as they were and puts them back,
and settles a drag or typing in progress first, as Undo does, instead of
running inside it and keeping its baseline as the batch's step. Files the
steps wrote stay written.
The renderer kept the evaluation of each blend, envelope and repeat
while the object and a hash stayed the same: the addresses of the art of
the symbols the object showed and of the patterns it painted with, and
the patterns' tile bounds. When anything else the evaluation reads
changed, such as a pattern's tile type, symbols in symbol art, the
fonts or the color settings, a renderer that had drawn the object went
on drawing the old evaluation. The quads of a gradient mesh were kept
the same way after a change to the color settings, and the art drawn
for a live object with an effect of its own was kept by the object's
address alone.
resources_key now also walks the opacity-mask, symbol and pattern art
it finds. It hashes what it finds, the font generation when it finds
type or a placed document, and the color settings. Mesh quads are made
again when the color settings change. The art drawn for an object's
effects is made again when the hash changes, if it was made from
evaluated live objects.
With other builds running, a temporary release test timed the hash for
400 live objects at 17 to 506 microseconds a frame, against 10 to 16
before.

A fully selected object is deleted along with partial anchors on other
paths. Several anchors on one closed path are removed by their original
indexes. What remains of a path stays selected, so a second Delete
removes it.
VectorCraft does not run scripts written for the reference app, and
File › Scripts held only the disabled Other Script…. File › Scripts ›
Check Script… picks a .jsx, .jsxinc or .jsxbin file, reads it without
running any of it, and shows a report: what the script needs (the
script language's own objects, the document model, files, menu
commands, dialogs, or features only the reference app has), what it
would do outside the document, the menu-command strings it passes, the
document-model member chains and type names it uses, its directives,
the files it includes, and the problems that would stop it loading.
Copy Report copies the report as JSON. File › Open and drag-and-drop
show the report for those files too.
- vectorcraft-scriptcheck, a new Standalone crate with no
dependencies, holds the checker: a lexer for ECMAScript 3 with E4X
literals and the #name and //@name directive lines, and an analysis
of the tokens that follows variables, function scopes and the files
a script includes. It never recurses: open brackets, the levels of
an XML literal and the function bodies being read are kept on stacks
capped at 4,096. It reads at most 8 MiB of a file and 32 MiB with the
included files, follows 64 included files 16 deep, looks up at most
1,024 paths for them, keeps 1,000 entries in a list, tracks 1,000
variables holding member chains and 1,000 holding File objects, and
cuts echoed text to 120 characters. A compiled script is reported as
compiled and isn't read.
- script.check (engine, a query) takes path, data or dataBase64. With a
path and includes: true, it reads the files the #include lines name
from inside the script's folder, through the automation read root,
and when the script or one of those files assigns a member chain or a
File object to a variable, the check treats the variable as holding
it in every file. It doesn't follow absolute names, names, folders or
links that lead out of the folder, names or folders longer than 4,096
bytes, or JSINCLUDE, and it reads only regular files.
- ui.checkScript shows the report (dialog scriptCheck). File › Open
lists Scripts (.jsx, .jsxinc, .jsxbin) and sends a script's path to
script.check, which reads at most 8 MiB of it.
The language rules come from ECMA-262 3rd edition and ECMA-357 2nd

from the public JavaScript Tools Guide and scripting guide pages that
catalog.rs cites by URL, and executeMenuCommand, doScript, loadAction,
unloadAction and selectTool come from the public forum posts cited
there; only names are used. Every script in the tests is written from
scratch with invented names.

document.open (and file.newFromTemplate) with a path relative to the
working directory took the SVG's folder from Path::parent(), which is
"" for a bare file name and was then dropped, so relatively linked
images were "not found" (and, linked by their bare name, not listed in
missingLinks either). A relative path is now made absolute first: its
folder is the working directory, as for the absolute path.
vectorcraft-cli convert printed only the export's warnings; what reading
the input left out now comes as importWarnings.
Fixes#1604
A character style's OpenType features took nine tags. OtFeatures now
also keeps ss01-ss20, salt, titl, pnum, lnum, sups and subs (off by
default, one bit each in `extra`): they are accepted by the type
commands, stored with the style and passed to the shaper, so a font
that has them uses them.
The Affinity import test used ss01 as its example of a feature kept but
not rendered; it now uses cv01 for that (character variants still
aren't rendered) and keeps ss01 as one that is.
Fixes#1607
Paste read PDF only from the Windows clipboard and EPS nowhere, so on macOS a copied
equation or drawing pasted nothing new (the last thing copied in the app came back).
- macOS: the pasteboard's PDF, EPS and SVG are read, ahead of text and bitmaps.
- Windows: EPS is read beside PDF.
- Everywhere: an .eps file copied in a file manager pastes.
- clipboard.importEps loads an EPS into the clipboard as document.open reads one.
The renderer kept the rasters of an object's drop shadows, outer glows
and filtered content (Gaussian Blur, Feather and the Photoshop-style
filters), and drew them again while the object, the zoom and rotation
and the ink plane stayed the same. The content drawn into a raster also
reads things outside the object: patterns, symbols, brushes, images,
document, layer and color settings, the knockout a group inherits, the
fonts, and the options the frame is drawn with. When one of them
changed, a renderer that had drawn the object went on drawing the
raster it had kept, made from the old values.
Each kept raster now records what its content was drawn from: which of
those things the object reads, found by walking the object when the
raster is made, and a hash of their values then. The renderer draws
the raster only while that hash is the same in the current frame. Once
a frame, the renderer hashes the document's patterns, symbols and
images. It hashes their art and pixels by the addresses of their
shared values, and it keeps weak references to those values while a
raster made with them is kept, so no other value can take one of those
addresses. A filtered raster also records the color channels its
filters split, and under De-Interlace the raster resolution.
A temporary release test timed the inputs of 400 kept rasters at about
10 microseconds a frame.
Opening an EPS whose threaded area type frame has a control point at
x = 8e115 failed with an internal error ("capacity overflow").
`eps_text_frames_never_panic` in `import_fuzz` found it with
PROPTEST_CASES=20000. Text layout flattens a frame to within 0.1 pt,
and for such a curve kurbo 0.13.1's `flatten` calls `reserve` for
`usize::MAX` quadratic pieces. Laying out text around a wrap shape with
such a curve failed the same way. Laying out type on a path along such
a curve panicked in kurbo's `solve_itp` ("attempt to shift left with
overflow") in builds with overflow checks, and in a release build it
did not finish within 20 s. Laying out area type in a triangle frame
that comes to a point at its top, at y = 1e20, did not finish either:
adding a lead to a baseline that large leaves the baseline where it is.
Text layout now leaves out a frame, a text wrap shape or the path of
type on a path that has a coordinate beyond 1,000,000,000 pt either
way, control points included, or a NaN coordinate in an anchor point.
Such a frame or path holds no text, and such a wrap shape is ignored.
PDF export uses the same bound (`MAX_COORD` in
`crates/pdf/src/export.rs`).
Text layout also steps a line down a frame cell at most 100,000 times
to find room for it. In a cell taller than 100,000 leads, a step is the
cell's height divided by 100,000; in a shorter cell, a step is one
lead, as before. Before this change, in a dev build, with triangle
frames that come to a point at their top, laying out text in one
2,000,000,000 pt tall took 9.8 s, and laying out a paragraph whose
Space Before is -1e300 pt in one 1,000 pt tall did not finish within
20 s.
- The type in a text object's drawn look (1 /FreeUndo) is a story of the
undo-free text document, which counts its stories on its own. It was read
as the story of that number in the text document, so a label could show
another object's text in another object's frame. The object itself, which
follows the look, is the type now.
- The page's type of a text object on a hidden layer stays with that object
(hidden) instead of going to the nearest text object that shows.
- The type on the page of a later artboard is matched where the layers have
that artboard, not by the first page's place.
The editing data places a gradient with matrices after Bg: Xm for a linear
gradient's whole ramp and one Bm for each pair of stops next to each other.
The reader kept the last Bm, so a gradient of three stops drew only its last
part. It now uses Xm (or, without one, the span of the Bm's from the first
stop to the last), and a radial gradient's one Bm as before. The angle and
length are in the matrices, so Bg's own numbers are used only without them.
An object's own note of its gradient after it (Bb, Bg, BB with no path) no
longer becomes the fill of the next path.
A .ai file with placed files opened from its PDF part (no guides, no sublayers,
no hidden objects), because the editing-data reader stopped at them.
- Lexer: a placed file's preview section is one token (it was skipped).
- Reader: %AI5_BeginPlace ... ~ becomes a linked image with the file's path,
showing the preview the data keeps of it (premultiplied ARGB, capped at
MAX_PIXELS, its rows checked against the bytes there), in its place: the
matrix takes the file's pixels from the canvas, where they start at the point
of art space's origin. A placed file without a preview, a path or a matrix
still makes the file open from its PDF part.
- The open result lists one warning saying linked pictures show the
low-resolution preview until their files are found (rows in the catalogs).
- Engine: a link nothing is known of whose image shows a preview is read where
it is found as the document opens, into the image's bounds, and isn't
reported as modified.
- Tests: lexer, reader (hand-written data), engine open with the link missing
and found, fuzz tokens.

Unlocked rectangle corners now each use their own radius and type (top left,
top right, bottom right, bottom left) instead of all following the first one,
and straight corners are cut across instead of rounded. patchy-shapes.af now
matches its embedded thumbnail (mean difference 1.91 -> 0.24) with no warning.

In builds with overflow checks (`cargo run`, `cargo test` and
`cargo xtask ci`), PDF export aborted the process when a number it
wrote rounded to -2,147,483,648 as an f32. pdf-writer 0.15 writes
-2,147,483,648.0 as an integer, and `Limits::register_int` overflows
when it takes the absolute value. krilla 0.8.2's `Surface` then fails
an assertion in its `Drop` while that panic unwinds.
`svg_hostile_markup_never_panics` in `import_fuzz` hit it with type
shifted 2,147,483,649 pt down. Paths, gradients, dash offsets, images
and artboards that far out hit it too, and so does a group around a
stroke wide enough to reach that far. Release builds have no overflow
checks.
PDF export now leaves out art whose coordinates or transform entries
lie beyond 1,000,000,000 in its own space or in the content stream it
is drawn into, and glyph lines whose spacing lies beyond 1,000,000,000
thousandths of an em. That covers paths and clipping paths, glyph
lines, images, gradients, strokes whose width, caps or miter spikes
reach that far, and the art and marks of a page whose artboard lies
that far, which is written blank. A dash offset beyond the bound is
written as its remainder after whole periods of the pattern.
The type's transform is now pushed inside the form that marks a fill
or stroke of type to overprint. The exporter checks what that form
holds through the type's transform, as it checks the same fill or
stroke without overprint.
A PDF saved with the reference app's editing data keeps that data in
streams named AIPDFPrivateData1, AIPDFPrivateData2, ..., where a .ai
file uses AIPrivateData1, AIPrivateData2, .... illustrator_data read
only the .ai names, so such a PDF opened like any other PDF: plain
groups opened ungrouped, and hidden objects and guides were missing. The
import gave no warning that the PDF's editing data went unread.
illustrator_data now reads the AIPDFPrivateData streams when the file
has no AIPrivateData1, and the PDF opens from its editing data as a .ai
file does. editingData: false still opens it like any other PDF.
has_private_data still looks for AIPrivateData keys only.
layered_ai also returns whether it read the layers. When it did, art
reaching past a PDF's page opens whole, and through_editing_data drops
the PDF importer's note that such art was clipped (PAST_PAGE_NOTE, now
public) as it drops the off-artboard note. When it didn't, both notes
stay. On main, a .ai whose editing data can't be decoded or has no
layers opened from its PDF part without the off-artboard note.
testkit::ai::pdf writes the .ai file of testkit::ai::ai with the PDF
key names. The editing-data tests open it as a PDF, and the import fuzz
test opens the damaged sample as a PDF too.
Docs: the document.open params, docs/mcp.md,
docs/file-format-parity.md, docs/gaps.md (G9: the export direction of
#868 remains), one evidence line in docs/target-app-parity.md, and #868
moved from layer structure to editing data in the File formats row of
docs/target-app-parity.md and in docs/roadmap.md.
History was limited by step count only; a whole-selection move of 50k paths keeps ~40 MB per
step. Steps now carry a size estimate (only unshared subtrees are visited) and the oldest are
dropped beyond a byte budget, keeping the last 8. Documents entering history drop their id
index, selections are shared between steps, the command journal is bounded (held while an
Action records), and document resources are copy-on-write. Saved files are byte-identical.

The engine's guard turns a panic inside a command into
EngineError::Internal and rolls the document back. The panic checks in
command_sweep.rs counted that error like any other error. They include
probe, which the empty-params, junk-params and structured-junk sweeps
call. The tests in import_fuzz.rs that open, place or paste a file
through a command counted it the same way. None of them reported the
panic.
Each of these checks now passes the command's result through no_panic,
which the library file tests in import_fuzz.rs already use, and the
change adds a copy of it to command_sweep.rs. A case whose command
panics now fails. The panic from no_panic reads "<command> panicked:
<message>", and the checks that print a panic's message show it. Each
check handles any other error as before.
Agents could set and clear the key object but not read it:
document.inspect, the control channel's ui.pointer reply and the
headless pointer_gesture reply left it out, and select.key returned
null. select.key with an id that was not selected, or with a value
that is not an id, such as "x", cleared the key without an error. A
compound-path member or an object inside a selected group could become
the key.
select.key now checks its id as select.set, select.add and
select.toggle do (#784). It returns an error for an id that is not a
selected top-level object and leaves the key as it was. Layers,
compound-path members and objects inside another selected object are
not top-level objects. select.key {id: null} used to clear the key and
is now an error; select.key {} still clears it. select.key returns
{key}, and document.inspect and both pointer replies include the key
object as "key".
In isolation mode a Selection-tool click can pick an object that
select.key does not accept as the key: a sublayer inside an isolated
layer, a member inside an isolated compound path, or an object in an
isolated group that is also selected. The tool no longer sends
select.key {id} for such an object. When the object is already the
key, the tool still sends select.key {}, which clears the key.
A recorded action whose select.key step names an object that is not a
selected top-level object when the action plays now fails and is
rolled back, as an action with a select.set step naming a deleted
object has failed since #784.
Docs: docs/mcp.md, docs/control-protocol.md, docs/target-app-parity.md.
The Anchor Point tool drags any segment of a selected blend's spine into
a curve, straight ones too, and Direct Selection reshapes a curved spine
segment as it does a path's (a straight one it leaves, as on paths). Both
run the new `object.blend.spine.reshapeSegment`, which bends the segment
with the same math as `path.reshapeSegment`, now shared as
`SubPath::bend_segment`.

object.align with neither horizontal nor vertical returned success
and moved nothing. The command palette, and a key bound to it in
Keyboard Shortcuts, run it with no params. It now returns
"give horizontal or vertical", as object.distribute already did.
An action recorded while Align ran from the palette or a bound key
contains an object.align step with no params. Playing that action now
fails at that step, and command.batch rolls back the whole action.
Values outside a parameter's choices were read as another choice or
ignored. Align ignored an unknown horizontal or vertical and aligned
to the selection for an unknown to value. Distribute read an unknown
direction as center. Distribute Spacing and Shear read any axis other
than "vertical" as horizontal, and Reflect read any axis other than
"horizontal" or a number as vertical. A bounds or to value that was
not a string fell back to the default, and a spacing that was not a
number gave automatic spacing. The commands now return an error that
names such a value, before they move anything or record an undo
step. When a to, bounds, axis or spacing value is missing or null,
the command uses the parameter's default: Distribute Spacing without
an axis spaces the objects horizontally.
The run_command description and docs/mcp.md showed object.align with
an align param it does not have; they now use horizontal. The new
status-bar messages have rows in the de, es, fr, it, ja, ru and uk
catalogs.
Docs: docs/mcp.md, docs/target-app-parity.md.
The sweeps `every_command_with_junk_params` and
`fuzzed_calls_keep_documents_serializable` skipped every case that set
`object.scale`'s `sx`, `object.transformEach`'s `scaleH` or `scaleV`,
`object.distributeSpacing`'s `spacing`, or `artboard.setProps`'s `x`,
`y`, `width` or `height`. The comment above `KNOWN_BUGS`, the list of
those (command, param) pairs, referred to `#[ignore]`d repro tests, but
`bug_huge_transform_makes_document_unloadable` and
`bug_artboard_huge_props_break_svg` have no `#[ignore]` and run with the
other tests. Since 42df20ca, the commit that added the list,
`Session::edit` returns an error when an edit leaves an artboard or a
selected object with coordinates that are not finite or exceed
`MAX_COORD`, and `object.transformEach` clamps `scaleH` and `scaleV`.
The list and its two checks are removed, so both sweeps run those
cases.
A .ai in PostScript form went only to the PostScript interpreter, which
stopped on the first operator its missing prolog would define
(`Adobe_packedarray`, `Lb`, `Np`): files from Rhino and other CAD apps name
the procsets without including them.
- Such a program is its own editing data: when it has layers
(`%AI5_BeginLayer`) and no private data, the editing-data reader reads it,
compared with the page when the program runs, from the layers alone when
it can't be run. If the layers can't be read either, the error says why.
- The reader takes the legacy ten-operand `Lb`, ignores flatness `i`, and
uses the bounding box as the page when nothing else says where it is.
- Tests on synthetic files; fuzz fixture and hostile-program layers added.

The editing-data reader stopped on `Xk`/`XK` (global process colours) and
on `p`/`P` (pattern fills), so the file fell back to its PDF part, which has
only the top-level layers.
- `Xk`/`XK` read like `Xx`: a global swatch (not a spot ink), linked at its tint.
- `%AI3_BeginPattern` sections are read by a reader of their own into
pattern swatches (tile from `(name) llx lly urx ury`, art in pattern space);
`p`/`P` fill or stroke with them, placed by the operator's matrix. A pattern
it can't read whole still makes a fill with it unreadable, as before.
- Tests on synthetic editing data; fuzz tokens and fixture extended.

Eight raster effects on the pixel-filter pipeline
(vectorcraft_effects::pixel::brushstrokes), under a new Effect › Brush
Strokes submenu between Blur and Distort in the Raster Effects section:
- Accented Edges (edgeWidth pt 1..14, default 2; edgeBrightness 0..50,
38; smoothness 1..15, 5): the edges of the softened object painted
towards white chalk at high brightness or black ink at low brightness;
Smoothness also leaves the faint edges out. The shape stays as it was.
- Angled Strokes (directionBalance 0..100, 50; strokeLength pt 3..50, 15;
sharpness 0..10, 3): light areas in right diagonal strokes, dark areas
in left diagonal ones; 0 makes every stroke a left diagonal, 100 every
stroke a right diagonal. Sharpness brings detail and bristles back.
- Crosshatch (strokeLength pt 3..50, 9; sharpness 0..20, 6; strength
1..3, 1): the detail kept under pencil hatching along both diagonals,
Strength passes of it, the edges roughened.
- Dark Strokes (balance 0..10, 5; blackIntensity 0..10, 6;
whiteIntensity 0..10, 2): short strokes towards black in the dark
areas, long strokes towards white in the light areas.
- Ink Outlines (strokeLength pt 1..50, 4; darkIntensity 0..50, 20;
lightIntensity 0..50, 10): black outlines over the edges, ink hatching
in the shadows, shadows darkened and highlights lightened.
- Spatter (sprayRadius pt 0..25, 10; smoothness 1..15, 5): each pixel
shifted by noise up to 0.4 x the radius; Smoothness makes the grains
larger and smoother.
- Sprayed Strokes (strokeLength pt 0..20, 12; sprayRadius pt 0..25, 7;
strokeDirection Right Diagonal, Horizontal, Left Diagonal or Vertical):
strokes along the direction, scattered by up to 0.3 x the radius.
- Sumi-e (strokeWidth pt 3..15, 10; strokePressure 0..15, 2; contrast
0..40, 16): wet strokes, ink bleeding from the darks along paper
fibres, more ink with pressure and an S-curve contrast for rich blacks.
It works in value only: hues and saturation stay, and so does the
object's shape (no fringe in the transparency).
A stroke averages the colour along a segment through the pixel (16
samples at most, the art softened first when they lie more than a pixel
apart); strokes lie in rows around the object's centre, each row
starting at random and each stroke shifted along itself, with streaked
noise for the bristles. Everything is in document space, so the effects
look the same at any zoom or resolution, move with the object and draw
the same every time; outsets and reaches are exact. On a 2000 x 2000
raster in release the slowest settings take 0.3-2.0 s (Crosshatch at
50 pt with 3 passes the most).
Shared helpers instead of copies: edges::sobel (Glowing Edges now uses
it, unchanged), distort::displace and texture::Tones are pub(super).
Catalogue rows with parameter docs, menu entries, Sprayed Strokes'
direction dropdown, translations (de, es, fr, it, ja, ru, uk, zh-hans,
zh-hant; menu labels in cs and pt-br), tests (parameters and clamping,
outsets and reaches, each filter and option showing, chalk and ink on
the edges only, shadows and rich blacks, Sumi-e keeping the shape and
hues, hatching keeping the tone, strokes smearing along their direction,
Spatter's radius, resolution and move invariance, canvas, multithreaded,
PDF and SVG, the command sweep with junk parameters, the menu) and

Three raster effects on the pixel-filter pipeline
(vectorcraft_effects::pixel::distort), under a new Effect › Distort
submenu between Blur and Pixelate in the Raster Effects section (the
vector Distort & Transform stays its own submenu):
- Diffuse Glow (graininess 0..10, default 6; glowAmount 0..20, 10;
clearAmount 0..20, 15): the highlights, softened over 2 points, glow
white from the brightness Clear Amount leaves clear; white grain as
dense as Graininess says is sprinkled over the object, thicker in the
glow. Transparency stays as it was.
- Glass (distortion 0..20, 5; smoothness 1..15, 3; texture Blocks,
Canvas, Frosted or Tiny Lens, default Frosted; scaling % 50..200, 100;
invert): the object seen through a glass surface; each pixel takes the
colour the surface's slope bends it to, sampled between pixels. Slopes
are taken over a span Smoothness widens. The surfaces are made in code
(Canvas is Texturizer's weave); Load Texture is left out.
- Ocean Ripple (rippleSize 1..15, 9; rippleMagnitude 0..20, 9): smooth
noise ripples about Ripple Size + 2 points across shift the object by
up to 0.03 x magnitude x their size.
The shifts are capped, so the effects' outsets and reaches are exact,
and every surface lies in document space around the object's centre:
the same at any zoom or resolution, moving with the object, identical
on every redraw.
Catalogue rows with parameter docs, menu entries, the Texture dropdown,
translations (and German's missing Canvas), tests (parameters and
clamping, outsets, each texture and Invert, the ripples' reach, the glow
and its grain, resolution and move invariance, canvas, multithreaded,
PDF and SVG, the command sweep with junk parameters, the menu) and
ROADMAP.
