A piece linked to a global swatch is drawn in the swatch's current color at its own tint, and kept art and rasters follow a color or spot edit and its Undo. A value of `paintOutput` other than true is refused by a translated error. Tests in the effects crate pass the new document argument.
A key that a paint does not have, such as `opacity` on a solid fill, was
dropped when the paint was read, and the fill was drawn opaque. The
result is now refused and `lastError` names the field, for keys on the
paint and on its colors, gradient, stops, placement and freeform points.
A live effect whose manifest has "api": 2 and "paintOutput": true returns
{"objects": [...]} as pieces, each drawn by itself in order with fills and
strokes of its own in the forms a filter returns. A piece without fills or
strokes keeps the ones the effect was given, and an empty list paints none.
An effect on a fill returns only fills, one on a stroke only strokes.
The whole result is checked before any of it is drawn: the output limits,
finite numbers in range with nothing clamped, known keys only, and every
swatch and pattern it names in the document. One fault draws that step of
the stack unchanged, keeps the effect record and puts the plug-in's name
and the field in plugin.info's lastError. Each piece counts against the
geometry-effect budget, so the painted effects of one stack make at most
100,000 pieces.
The pieces are drawn, measured and exported to PDF and SVG from the
appearance stack without changing the document, and Expand Appearance
writes them as ordinary paths in one undo step. The plug-in API level
rises to 2; plugin.list and plugin.info give api and paintOutput. Effects
without the key behave as before.
