G2: Effect › Artistic › Cutout, Neon Glow and Poster Edges

Three original Artistic filters on the pixel pipeline, each with a
catalogue row, the generic live dialog, translations and tests.

- Cutout: colours softened by Edge Simplicity (less with Edge Fidelity),
  split into Number of Levels steps per channel and painted as flat
  pieces in their average colour; slivers along softened edges take the
  nearest large piece's colour.
- Poster Edges: channels posterized to Posterization + 2 levels, black
  lines on the edges of any channel and of the outline, widened by Edge
  Thickness and darkened by Edge Intensity.
- Neon Glow: dimmed greys screened with a glow colour from the light
  areas (positive Glow Size) or the dark ones (negative), as strong as
  Glow Brightness.

All keep coverage and work in document units at any Document Raster
Effects resolution. Photoshop filters 33/57; cargo xtask ci passes all
9 steps.

+Cutout, Neon Glow and Poster Edges (`artistic.cutout`, `artistic.neonGlow`, `artistic.posterEdges`)
+follow the same two public references, with original algorithms. Cutout softens the object's colours (Edge Simplicity, less with Edge
+Fidelity), splits each colour channel into Number of Levels steps, and paints each resulting piece
+in the average colour that falls into it, so hues survive. Poster Edges
+posterizes each colour channel to Posterization + 2 levels and draws black lines on the edges of
+any channel and of the object's outline, wider with Edge Thickness and darker, on fainter edges
+too, with Edge Intensity. Neon Glow redraws the object in dimmed greys screened with a glow colour
+from its light areas (positive Glow Size) or its dark ones (negative), spread by the size and as
+strong as Glow Brightness; with no foreground and background colours in Illustrator's model, the
+glow colour is the effect's own parameter. All three keep coverage, work in document units at any
+Document Raster Effects resolution, and use the generic effect dialog with live preview. Ranges and

+and `artistic_settings_survive_a_save_and_open` in `crates/engine/src/tests_rasterfilters.rs`.
 Near white, highlight headroom can limit grain equally at every Intensity; highlight lift still
 depends on Intensity when Highlight Area is nonzero.
