With the Linear mode, two problems kept a click on an anchor from
taking it:
- A press on an anchor that moved more than 3 pixels before the release
dragged out the dimension of the segment under the pointer and
committed it almost on top of the art. A press on an anchor now picks
it unless the pointer moves past the anchor's 8-pixel reach; a longer
drag still dimensions the segment.
- A pick linked only an anchor of the segment nearest the pointer. An
anchor of another path near that segment, for example one inside a
group lying just inside another object's edge, was taken at most as a
Smart Guides point with no link, so the dimension did not follow it
when the art changed. A pick now links the nearest anchor of any
visible, unlocked path within reach, in groups and compound paths too.
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.
Picking the two points of a Linear dimension snapped to anchors and to the
line under the pointer, but showed no guides and ignored the art around it.
The picks now go through the drawing tools' Smart Guides (DrawSnap), hovering
too, so the guides show before each click: a point slides into line with other
objects' anchors and centres, and the second onto the construction guides
through the first. An anchor of the line under the pointer still wins (it
links the dimension to that path), then a guide, then the closest point of the
line (#2432). The guides go once the dimension is being placed.
Test: linear_picks_show_and_snap_to_smart_guides (fails on the old tool, which
showed no overlays while hovering). docs/dimensions.md updated.

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.
