Guides dragged out of the rulers could not be touched again: no tool hit-tested
them, so a click on a guide went to the art under it.
- The Selection, Direct Selection and Group Selection tools pick a ruler guide
within the selection tolerance (over the art; Direct Selection takes an
anchor on it first) through a shared tools::rulerguide::GuideEdit. A drag
moves the selected guides in one undo step (Alt copies them, Shift snaps the
dragged one to the ruler's ticks, otherwise it snaps to pixels, the grid or,
with Smart Guides, the art's edges, centres and anchors); dropped off the
canvas onto its ruler, the guide is deleted. Hidden or locked guides can't be
picked; the pointer shows which way a guide moves.
- Selection::guides holds the selected guides (on their own, like slices); the
canvas draws them in the selection colour. Delete/Backspace (edit.clear)
delete them, the arrow keys (object.nudge) nudge them, Lock Guides and Hide
Guides deselect them.
- Commands for agents: guide.list, guide.select {indexes, toggle?},
guide.move {dx?, dy?, copy?} (besides {index, pos}) and guide.remove {index?};
guide positions out of range are refused. Documented in docs/mcp.md.
- Shift while dragging a new guide out of a ruler snaps it to the ticks too
(Unit::ruler_step, shared with the rulers' drawing).
