bflatastic 30ba774e6f Part of gap 2: Effect › Texture (Craquelure, Grain, Mosaic Tiles, Patchwork, Stained Glass, Texturizer)
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.
