Docs: a clipping path that paints applies its fill and stroke effects after the group's

The geometry effects of a clipping path's own fills and strokes stay live when the clipping path has a fill or stroke, so they reshape it after the geometry effects of the clip group and of the groups around it.

    Object › Expand Appearance keeps each stroke of a path a stroke (weight, caps, joins, dashes, arrowheads, alignment and width profile) on a copy of the path with the geometry effects baked in, and Object › Expand… is dimmed, with a tooltip, while the selection has appearance attributes, so a stroked line with Zig Zag becomes a stroked zig-zag line and only Expand then outlines it, the two steps the [Expand objects](https://helpx.adobe.com/illustrator/desktop/manage-objects/arrange-objects/expand-objects.html) help page describes (#3089). Brushed strokes still become their brush art; `object.expand` still bakes and outlines in one step for agents.
  - **Masks and clipping:** opacity-mask controls work while the mask is being edited; transparency commands take ids and work without a selection; clipping sets clip by compound paths, even-odd paths, text and groups on screen and in raster export, matching SVG/PDF. Alt-click shows only the mask; SVG masks keep Clip and Invert; the transparency grid is per-document state; a clipping path's own fill and stroke paint behind and over the clipped art; layers can be clipping masks.

-    The geometry effects of a clipping path (Roughen, Transform and the other effects that reshape a path), of its fills and strokes, and of the members of a group used as one, shape the area it clips to on the canvas and in raster export, as in SVG and PDF export: a roughened clipping path clips by its roughened outline. They apply before the geometry effects of the clip group or of a group around it, on the canvas and in every export, and type used as a clipping path keeps them when a group's effect outlines it. Raster effects such as Gaussian Blur leave that area as it is. `effects::tests::clipfx` and the renderer's `tests::clip` cover it.
+    The geometry effects of a clipping path (Roughen, Transform and the other effects that reshape a path), of its fills and strokes, and of the members of a group used as one, shape the area it clips to on the canvas and in raster export, as in SVG and PDF export: a roughened clipping path clips by its roughened outline. They apply before the geometry effects of the clip group or of a group around it, on the canvas and in every export. When the clipping path has a fill or stroke of its own, the geometry effects of those fills and strokes apply after the group's geometry effects instead. Type used as a clipping path keeps its geometry effects when a group's effect outlines it. Raster effects such as Gaussian Blur leave that area as it is. `effects::tests::clipfx` and the renderer's `tests::clip` cover it.
    Clicks, Select Behind, the Unlock submenu, marquees and the Enclosing Lasso inside a clip group or a clipping layer follow that area too: the clipped art is found where the effects moved it and not where they took it away. The clipping path itself is still found by its own outline and anchors. Outline view and layers with Preview off draw the plain clipping path, and clicks and marquees there count it. `doc::hit::tests` and the engine's `tests::clip` cover it.
  - **Transparency:** three-state Knockout Group (on, neutral, off), Opacity & Mask Define Knockout Shape, Page Isolated Blending and Page Knockout Group, on screen and in SVG/PDF. SVG export writes a knockout group of opaque art plainly, without masks, so shapes meeting edge to edge leave no seam; translucent, blended, masked or brushed art knocks out through masks. Blend modes match the standard formulas on screen, in SVG and in PDF, and non-isolated groups blend with the art below. Flatten Transparency with presets, a dialog and a Flattener Preview panel. Flattening for files without transparency (PDF/X-1a, PDF/X-3) in a CMYK document keeps the inks where it rasterizes, as under an image with see-through pixels: the images it makes hold ink amounts, not screen colours the file would separate again, so a C100 M6 Y41 K3 panel stays C100 M6 Y41 K3 there (#2160, `engine/src/cmd/fileio/tests_pdfx.rs`).
    On the canvas, the renderer no longer draws the picture of the art below back as an image each time it copies the backdrop of a non-isolated group that blends: it keeps that picture and draws the art that follows over it. At 2880 × 1800, 50 translucent groups with Multiply members take 65 ms a frame instead of 299 ms on 8 threads (`vectorcraft-cli bench`), and the frames have the same pixels.
