With the Gradient tool on a freeform gradient the selected point shows its
spread as a dashed ring with a handle; dragging either sets the spread. A
point dragged out of the object is removed on release, and double-clicking a
point opens the gradientStop popover, which now edits the selected freeform
point (colour, opacity, spread). In Lines mode successive clicks draw one
smooth line (with a rubber band to the pointer); clicking an existing point
continues the line from it, and Escape or a click off the art ends it.

paint.freeform.addPoint/setPoint/deletePoint/addLine/splitLine/selectPoint
and the paint.freeform.get query edit the freeform gradient behind the active
proxy (one undo step each; errors on other paints). The session keeps the
selected point. The Gradient tool on a freeform gradient selects and drags
points, adds points on the art (joined in Lines mode) and on lines, and
deletes the selected point. The Gradient panel shows the Draw toggle and the
selected point's colour, opacity, spread and Delete Point; the Color panel
recolours the selected point.

Freeform gradients carry their own points (colour, opacity, spread) and lines
(Catmull-Rom curves through points), blended by inverse-distance weighting
from each disc of pure colour. paint.editGradient {kind: "freeform", mode?}
places 4+ points inside the shape, coloured along the stops (which follow the
points' colours). The renderer samples the field on a cached colour grid
drawn as an image paint clipped by the fill or stroke. Moves, transforms,
box rebases and warps move the points; old files load unchanged.
