Effects: Smart Blur's Mode menu has Edge Only and Overlay Edge

Effect › Blur › Smart Blur had only its Normal mode: the dialog and
blur.smart took Radius, Threshold and Quality and drew the blur.

Smart Blur now takes a `blurMode` param ("normal", "edgeOnly" or
"overlayEdge"; "normal" by default), which its dialog shows as a Mode
menu. Edge Only draws the edges in white on black, and Overlay Edge
draws them in white over the Normal blur. A pixel is on an edge when
one of its four nearest pixels differs from it by more than the
threshold in a channel and its channels, alpha included, add up to at
least that pixel's. The white and the black keep each pixel's
coverage. Normal draws the same pixels as before, and an effect saved
without `blurMode` draws as Normal.

 - **Texture redraws (#1257):** Craquelure, Mosaic Tiles and Stained Glass compare squared distances when finding their nearest cells; rounding/tie boundaries use the original distance ordering. Brute-force candidate tests and three 1800×1500 viewport comparisons preserve the old pixels. A CMYK rectangle move at 190.07%/DPI 1.5 is reproducible with `cargo test -p vectorcraft-render texture_drag_perf -- --ignored --nocapture`; idle-machine Windows interaction is still unverified.
 
+- **Smart Blur modes:** Effect › Blur › Smart Blur… has a Mode menu with Normal, Edge Only and Overlay Edge (`blurMode`: `normal`, `edgeOnly` or `overlayEdge`; an effect saved without it draws as Normal). Edge Only draws the edges in white on black, and Overlay Edge draws them in white over the Normal blur. A pixel is on an edge when one of its four nearest pixels differs from it by more than Threshold in a channel and its channels, alpha included, add up to at least that pixel's, so a color step gives a line one pixel wide on the side with the larger sum (two pixels when the sums are equal). The white and the black keep each pixel's coverage, and Radius changes only the blur. Behavior reference: [Summary of effects](https://helpx.adobe.com/illustrator/using/summary-effects.html).

 - **Moving objects with raster effects (#1257):** during a drag or a dialog's preview, an object whose content only moved draws its cached drop shadows, outer glows and filtered content (Gaussian Blur, Feather and the Photoshop-style filters) from the rasters of an earlier frame at the nearest whole pixel, without running the effects again. The renderer first draws the moved content where the old content lies in its raster and compares the pixels. De-Interlace runs again. The frame after the drag runs the effects again and draws what a fresh renderer draws; on the desktop, the canvas renders that frame on the render worker. `texture_drag_perf` times a drag's frames and the frame after it.
 
 - **Raster effects after document and view changes:** a cached drop shadow, outer glow or filtered content is made again when something its content reads from outside the object changes: a pattern's art or tiling, a symbol shown inside another symbol, a brush definition, an image's pixels, the raster resolution (De-Interlace), Page Knockout Group, Document Setup's substitution highlights, a layer's Dim Images, the color settings, the fonts, Pixel Preview, Anti-aliased Artwork, Overprint Preview and isolation mode. A thumbnail under Color Halftone or Mezzotint is made again when the document's color mode changes.
