A plug-in's dialog (Effect › Plug-ins, Object › Plug-ins) lays out each
parameter of its manifest as a row, and a manifest may declare up to 64.
With many of them the dialog ran off the top and the bottom of the
window, its heading and its OK and Cancel buttons off screen. A plug-in
of 64 number parameters got a dialog 2,329 px tall, its top at y = -755
in a 900 px window.
modal::scrolled_rows() puts rows in a vertical scroll area as tall as
the screen less the rest of the modal window and its edge gaps.
modal::show_at() measures that rest once it has drawn the window, for
the next frame, and asks for that frame at once if the rest changed.
The dialog then fits without waiting for input. schema_fields() puts the
parameter grid in it, for filters and effects alike. A dialog of a few
parameters is as tall as before.
a_plug_in_dialog_of_many_settings_fits_the_window opens an effect's and
a filter's dialog of 64 parameters in a 1280 × 900 window, and one of 4.
Before the change it failed with "effect: the dialog is at
[[457.0 -755.0] - [823.0 1574.0]] in the [1280.0 900.0] window".

Install Plug-in (plugin.install) now keeps the plug-in's module in a
Plug-ins folder next to the preferences, as Illustrator keeps plug-ins in
its Plug-ins folder, and the desktop app and vectorcraft-cli install the
ones there at startup (a module that doesn't load is skipped with a log
record, at most 512 MB are read). Remove Plug-in deletes it from the
folder. The Additional Plug-ins Folder preference is still loaded from
where it is. Confined MCP servers and VECTORCRAFT_NO_PREFS keep nothing,
as with the PDF preset and colour profile stores.
Docs: docs/mcp.md, docs/plugins.md, docs/target-app-parity.md.
VectorCraft had an Additional Plug-ins Folder preference but nothing loaded from it. Port
PhotoCraft's wasmi plug-in host (same sandbox, manifest and parameter schema) as the new
vectorcraft-plugins crate (L2), extended for vector documents:
- Object filters read the selected paths and compound paths as JSON (native PathData and
Paint forms: geometry, fills, strokes, gradients, opacity) and return the objects to keep,
change, add or delete; the output is validated in full and applied as one undo step
(plugin.run). A failing plug-in leaves the document untouched.
- Live-effect plug-ins are geometry effects in the appearance stack (effect id
plugin.<id>), re-evaluated (and cached) when the object or parameters change, editable,
exported and baked by Expand Appearance; a missing plug-in leaves the geometry as is.
- plugin.list / info / run / install / remove / reload; the preference folder installs
every *.wasm at startup and when it changes; File > Open of a .wasm installs it (web).
- Object > Plug-ins and Effect > Plug-ins menus with dialogs generated from the parameter
schema (live preview), the Appearance panel's fx menu, docs/plugins.md, an original
example plug-in (Desaturate, a Rust crate outside the workspace) and fuzzing of the
plug-in boundary (engine/tests/plugin_fuzz.rs).
Tool plug-ins and paint-changing live effects are left for later (docs/plugins.md).
