Graphs: invert and complement remember the equal row they recolor; document aligned

With a mixed selection and the Appearance panel's active row, paint.invert
and paint.complement recolor each object's row equal to the active one,
but remembered the color at the active row's index in the first object in
paint order, which can be another row. They now remember the row they
recolor there, as the gradient and freeform edits do.

The params text of paint.setFill, paint.setStroke, paint.invert,
paint.complement, paint.lastColor, paint.lastGradient, stroke.setAdvanced,
paint.editGradient, paint.setGradientGeom and the paint.freeform edits now
lists `aligned`. docs/mcp.md names paint.lastColor and paint.lastGradient,
which take the same rows as paint.setFill, and docs/target-app-parity.md
gets a line for the rows of a design's art.

   - **Graph column designs:** Object › Graph › Column (`graph.column`) draws the columns, bars or stacked segments and the legend swatch of the series picked with Group Selection with a graph design: Vertically Scaled stretches it to each column's length, Uniformly Scaled scales it both ways and centers it, Repeating stacks a copy for each Each Design Represents value and chops or scales the last one (For Fractions), and Sliding keeps the part above the design's guide line in proportion and stretches the part below. The dialog lists the designs with a preview; the choice is saved with the graph and follows the design's rename and delete.
     Type in a column design that holds a `%` followed by two digits shows each column's value in place of the `%` and the digits: the first digit is the least number of places before the decimal point (zeros are added in front; 0 gives as many as the value needs), and the second digit sets the places after it, rounded. Unless it is inside a group that clips or has its own opacity or appearance, or inside a blend, compound shape, envelope, repeat or intertwined objects, the type keeps its size and is drawn once per column in a repeating design. The legend swatch leaves it out.
     The transparency, paint, stroke, gradient and overprint commands and Expand Appearance also leave the art of a column or marker design inside a series unchanged. The graph draws that art again from the design (`docs/mcp.md`).
+    When that art is given first with `aligned: true`, the paint, stroke and gradient commands read the `item` as a row of the art's stack, and each other object edits its equal row.
