Object > Expand left a dimension's recipe on its group, so the next move
redrew the live dimension and discarded the expanded art. Expand now ends
the live link of a dimension whose art it changes, in the same undo step.
Moving or scaling the group leaves its art as it is, the art no longer
follows what it measured, and undo gives the live dimension back.
Expand Appearance, Create Outlines and Outline Stroke had the same fault
and now do the same, also when they reach only a part of a dimension. A
dimension whose art a command leaves as it was stays live. A dimension
selected with the art it measures becomes a plain group when Expand,
Expand Appearance or Outline Stroke replaces only that art.
Review follow-up (CodeRabbit): a text node's characters carry their own fill
(CharStyle), saved apart from the node's appearance, so conform also checks
the runs of the label. dimension_colours_follow_the_document_colour_model
opens a CMYK document whose label characters alone are RGB; without the
change they stay RGB.
Follow-up to #3702 (CodeRabbit): dimensions are only redrawn when their
recipe changes. Document Color Mode converted their art through the colour
profile, so black became a four-ink C67 M67 Y67 K100 again, and CMYK files
saved before #3702 kept RGB dimension art.
dimension::refresh now also redraws when the document's colour mode
changes. dimension::conform, run when a document is opened or reverted
(Session::add_document, replace_document), redraws a dimension whose art
has colours in the wrong model; one that can't be redrawn keeps its art.
dimension_colours_follow_the_document_colour_model covers RGB to CMYK and
back, and a CMYK document with RGB dimension art being opened. Without the
change it finds C0.67 M0.67 Y0.67 K1 after Document Color Mode.
Drag out from a segment, corner, circle or arc to place a dimension; plain clicks pick two points or two lines. Radial dimensions on perfect arcs, picas, Away/Between and Left/Center/Right text placement. The Properties panel edits a selected dimension, with Apply to All (dimension.applyToAll) and Set as Default. Dimension Selected Paths, the Arc/R/Ø prefixes and the custom defaults are left out. The refresh returns at once in documents without dimensions (Document::dimensions); a linked dimension moved on its own keeps its place; modes, units, line types, arrows and text placement are enums; the tool has its own icon.
