Effects: Effect › Rasterize draws an object as pixels while its paths stay editable

The Effect menu had no Rasterize. Object › Rasterize replaces the
object with an image, so its paths can no longer be edited.

Effect › Rasterize… (`rasterize`) is a live effect with Object ›
Rasterize's options: color model, resolution (the document's raster
effects resolution by default), white or transparent background,
anti-aliasing, Create Clipping Mask and Add Around Object. The canvas
draws the object as square pixels over its bounds, and its paths, type
and other art stay as they are. The effects above it in the stack,
shadows included, are part of its image, and shadows below it are cast
by the image. When Rasterize is an object's only raster effect, Expand
Appearance and PDF and SVG export give the image Object › Rasterize
gives with the same options.

Object › Rasterize now measures the art as drawn, with its geometry
effects, brush art and raster effects, so a Transform effect that moves
the art no longer leaves the image empty. Its Create Clipping Mask
clips the image to the art as drawn. The canvas no longer panics
drawing a pixel effect such as Gaussian Blur on an object about 65,500
screen pixels wide: the raster of such an object is at most 32,768
pixels a side, and the object is drawn into it at a lower resolution.

+`effect.apply {effect: "rasterize"}` (Effect › Rasterize…) draws an object as an image of square pixels while its
+paths, type and other art stay editable. It takes the options of Object › Rasterize under these names: `colorModel`
+(`document`, `grayscale` or `bitmap`), `useDocumentResolution` (true by default: the resolution above) or
+`resolution` (1 to 2400 ppi), `background` (`transparent` by default, or `white`), `antiAlias` (`art`, `type` or
+`none`), `clippingMask` and `addAround` (points). The image covers the object's bounds and the room around them,
+its first pixel at their top-left corner. Both `object.rasterize` and the effect measure the art as drawn: with its
+geometry effects, its brush art and its raster effects. The effects above Rasterize in the stack, shadows included,
+are part of the image, and the shadows and glows below it are cast by the image. The canvas draws an image of up to
+8.4 million pixels, at most 32,768 a side, on its own grid and then at the view's zoom: an image pixel wider than a
+screen pixel shows as one flat square, and smaller ones are averaged. A larger image is made from the art drawn at the canvas's resolution
+(lower for very large art), and its pixels no wider than a pixel of that drawing show the art as drawn.
+When Rasterize is an object's only raster effect, Expand Appearance and PDF and SVG export replace the object with the
+image `object.rasterize` makes with the same options.

 - **Malformed MCP replies:** invalid JSON from the app drops the connection, reports that the operation may have completed and leaves the next call to reconnect; it never replays the edit (#1761). TCP regressions cover malformed and uncorrelated replies, connection closure and a subsequent inspection. Envelope regressions also verify zero backend calls and unchanged initialization state for invalid versions.
 - **Tests and robustness:** ~2,840 automated tests: model-based property tests, a junk-parameter sweep over every command, import fuzzing (SVG, PDF, libraries), golden renders, and MCP end-to-end tests over stdio. Shipped code never panics (workspace lints and a rollback safety net; see `docs/development.md`). Scatter graph data near the largest number is refused with a message instead of hanging the app (#1780). One very long Liquify stroke segment can no longer create an unbounded number of dabs (#1779). A drag whose last preview failed is no longer recorded as a committed command in the journal that actions and scripts read (#1775). Tests: text import fuzzing no longer searches installed fonts (#1785). Tests: render tests that add fonts no longer race the frame cache tests (#1795).
 - **Raster-effect resolution in PDF:** when the 64 million pixel cap on an effect image renders an object's raster effects below the document's raster effects resolution, PDF export warns once per object with the requested and the lowest achieved ppi (`crates/engine/src/tests_pdfraster.rs`).
+- **Rasterize effect:** Effect › Rasterize… (`rasterize`) draws an object as an image of square pixels at its own resolution or the document's raster effects resolution, with Object › Rasterize's color model, background, anti-aliasing, clipping mask and room around the object, while its paths stay editable.

 - **Pattern tiles:** the renderer keeps a tile of each pattern for each scale it rasterizes the pattern at, until the tiles fill the tile cache's budget, and then drops the least recently used tiles first. Objects that show one pattern at different scales, such as a pattern scaled to 25% with Transform Pattern Tiles next to the same pattern at 100%, draw from tiles kept between frames.
