Window › Swatch Libraries › Patterns and the Swatches panel's library
menu gain Optical Effects (`optical-effects`), a built-in pattern library
of eight black tiles drawn in code: Sine Bands, Ripple Lines,
Interference Rings, Offset Rings, Warped Checks, Pinched Stripes,
Chevron Pulse and Radiating Lenses. The names and designs are
VectorCraft's own. Each tile is 32 to 48 pt, one period of its design,
with fixed sample counts (at most 600 paths and 20,000 segments), so a
band that leaves one edge comes back at the same place on the opposite
edge, and rings and lenses that cross an edge are kept whole for the
tiling to draw on the next tile. Clicking a swatch adds its pattern and
swatch once and applies it, as with Geometric Patterns
(`swatch.library.add`).
The menu label has a row in every catalog; docs/mcp.md, the parity doc
and ROADMAP name the library.
Window › Swatch Libraries › Patterns and the Swatches panel's library
menu gain a second built-in pattern library, Grit Textures, with eight
black textures on square grid tiles of 18 to 36 pt: Fine Grain, Coarse
Grit, Sand, Speckle, Stipple, Scratches, Sparse Flecks and Dense Flecks.
Each is drawn in code from a fixed seed, so it is the same every time.
Marks that reach past a tile edge are drawn on the next tile by the
tiling, so the tiles join without a seam.
Docs: docs/mcp.md, docs/target-app-parity.md, ROADMAP.
Follows #6592. Paste now also skips the names that effects in the
document's brush art use when it picks a free name for a pasted SVG
filter. When no free name keeps the filter within the 64 KB limit (a
one-letter name at the limit with every free letter and digit taken),
the paste is refused instead of keeping the name of the document's
filter. Clipboard::import_into and import_text_styles return a Result,
and their callers pass the error on before the document changes.

swatch.library.add looks for the library's pattern among the document's
patterns of that name or a numbered copy of it, instead of importing it
into a copy of the document. Only a swatch that paints with the pattern
unmoved counts as the pattern's swatch, so a swatch whose pattern was
moved in its space is not reused and applied in its place.
Window › Swatch Libraries and the Swatches panel's library menu get a
Patterns submenu with Geometric Patterns, a built-in library of eleven
black pattern swatches drawn in code (dots, stripes, a checkerboard, a
grid, diamonds, triangles, crosses and a zigzag).
- Clicking a pattern in its library panel adds the pattern and its
swatch to the document and applies it to the active fill or stroke
(Alt: the other one), as one undo step. A second click reuses the
swatch; a different pattern under the same name keeps its name and
the library's pattern comes in numbered.
- swatch.library.list lists the pattern libraries after the gradient
libraries (category "patterns"), and swatch.library.add brings a
pattern swatch's pattern as pasting art painted with it does.
- The library panel draws each pattern tile from the library's pattern.
- "Geometric Patterns" is translated in every catalog.
