Illustrator 30.0's gradient Dither, from the public documentation
(https://helpx.adobe.com/illustrator/desktop/paint-and-fill/create-and-edit-gradients/control-dither-in-gradients.html):
a Dither checkbox in the Gradient panel; dither converts the gradient into
pixels with subtle noise, works with gradient fills only, and follows the
Document Raster Effects resolution.

- Gradient gains `dither` (serde default false, written only when on, so
  older files open unchanged and new files keep it).
- The renderer draws a dithered linear or radial fill as an image paint: the
  gradient sampled a cell per device pixel or finer (quarter-octave steps,
  cached per thread), each channel given seeded triangular noise of up to a
  level before rounding. Same pixels every run; strokes and undithered fills
  draw exactly as before. PNG and other raster exports go through it.
- SVG and PDF write a dithered fill as an image at the document's raster
  effects resolution, clipped to the shape (the freeform-gradient path);
  characters' fills stay vector gradients in SVG, with a warning.
- paint.editGradient and paint.setFill take `dither`; strokes refuse it.
  The Gradient panel's Dither box is dimmed behind the Stroke proxy.
- i18n rows in all 24 catalogs; docs: G13, target-app-parity, ui-parity,
  mcp.md, plugins.md.
