These commands edited the document even when nothing changed, so the
call recorded an undo step, emptied Redo and marked the document
modified:
- Fill, Stroke, None, Apply Last Color and Apply Last Gradient with the
paint the objects have already, also on characters selected with the
Type tool.
- stroke.set and stroke.setAdvanced with the options the strokes have
already.
- paint.editGradient, paint.setGradientGeom and the freeform point
commands when the gradient comes out as it was.
- Invert and Complement on the Appearance panel's selected row when no
color changes.
- Swap Fill and Stroke and Default Fill and Stroke when every object
comes out as it was.
- appearance.setItem with the values the item has or an index no
object has, and transparency.set with an item and the values that
item has; appearance.removeItem with indices past every stack;
appearance.moveItem, Reduce to Basic Appearance, Clear Appearance,
the Eyedropper (appearance.copyFrom) and appearance.transfer when
every object comes out as it was.
These commands now return without editing the document. The replies
have the same form as before. On a graph's series or labels, a fill or
stroke that the art has already still records one undo step when the
graph does not keep that paint for them (for example after the
Eyedropper painted the art), and the graph then keeps it.
The Eyedropper test whose second copy changed nothing gives its target
a green fill first, which the copy turns red again.
One line in the evidence list of docs/target-app-parity.md names these
commands, apart from Invert and Complement.
