`artboard.setProps {scaleArt: true}` maps the art fully inside a resized
artboard (as Move Artwork with Artboard gathers it) and its artboard guides
from the old rectangle onto the new one, each side by its own ratio, in one
undo step, and returns the ids scaled. Strokes, effects and corners follow
Scale Strokes & Effects and Scale Corners (`strokes`, `corners`), pattern tiles
Transform Pattern Tiles (`patterns`); locked and hidden art follows
`lockedAndHidden` (default: prefs moveLockedWithArtboard). The resolved choices
are journaled, so a replay scales the same objects the same way. A move that
keeps the size scales nothing.
The Artboard tool's `scaleArt` option (saved with `moveArt`) makes handle
drags proportional, as the public help describes, keeps them proportional at
the 1 pt minimum, and leaves the scaled art out of the Smart Guide targets.
Move and Scale Artwork with Artboard are check boxes in the Control bar and
Properties' Edit Artboards; the artboard size fields there and in the
Transform panel pass the option. Translated in the eight catalogs that have
Move Artwork with Artboard. docs/mcp.md and the ROADMAP updated.
