A click with the Selection tool on a guide selected with objects makes
it the key (select.key {guide}), drawn thicker; a click on it again
cancels it. Align to Key Object is on with one object and a selected
guide and makes the guide the key. object.align lines the objects (or
selected anchors) up on the guide's line and leaves the guide where it
is: a vertical guide sets x only, a horizontal one y. The selection
keeps key_guide beside key, never both; it goes with the guide or the
objects, and follows the guide when earlier guides are deleted.
Distribute Spacing doesn't space from a key guide.
Zooming in on an inch ruler stepped through 0.2, 0.1 and 0.05 of an inch:
`Unit::ruler_step` picked from one decimal ladder for every unit, and the
rulers divided whatever it returned by ten. A tenth of an inch is not a mark an
inch ruler carries (#2827).
Below an inch the steps are binary fractions now, 1/2 down to 1/128, and
`Unit::ruler_minor` gives the unlabelled ticks between two labels: an eighth of
the step on an inch ruler, so every tick is a binary fraction of an inch and
they stay about as dense as the tenths elsewhere. An inch and wider keeps the
shared ladder, and the metric units, points, pixels and picas keep their
tenths. Ruler-tick snapping follows the ticks that are drawn, which moves an
inch document's Shift-drag of a guide onto the same grid.
`ruler_label` took its decimals from `(-step.log10()).ceil()`, which writes
1/16 as "0.06" and 1/8 as "0.13" -- wrong values, not just rounded ones. It
uses the fewest decimals that write the step exactly, and drops trailing zeros
as `Unit::number` does, so a sixteenth-inch ruler labels the inch `1` rather
than spelling `1.0000` down six lines of the vertical ruler.
View › Rulers › Change to Global Rulers (Cmd+Alt+R) was a disabled
stub: the rulers always counted from one document zero point. The
reference app's public help describes two modes: artboard rulers, the
default, count from the active artboard's top-left corner, and each
artboard can have its own zero point; global rulers keep one zero point
for the whole document whichever artboard is active.
https://helpx.adobe.com/illustrator/desktop/measure-and-align/grids-and-guides/about-rulers.htmlhttps://helpx.adobe.com/illustrator/desktop/measure-and-align/grids-and-guides/use-rulers.html
`view.globalRulers {global?}` switches the mode (toggle by default),
undoable and saved with the document (`rulers`). The menu item reads
Change to Artboard Rulers while global rulers are on. A new document has
artboard rulers; a file saved before the mode existed has no `rulers`
key and opens with global rulers, so it measures as it did.
With artboard rulers, dragging the ruler corner sets the active
artboard's zero point, kept as an offset from its corner
(`artboard_ruler_origins`, by artboard id) so it moves with the
artboard, and double-clicking the corner resets it. The global zero
point (`ruler_origin`) stays separate. `document.rulerOrigin`,
`document.setRulerOrigin` and `document.resetRulerOrigin` take
`artboard`; `Document::ruler_origin_for` is the zero point with an
artboard active, falling back to the corner or the global one when a
stored value is out of range.
The rulers, the Transform, Properties and Control bar X/Y, the Info
panel's X/Y (which ignored the zero point before), ruler-guide
readouts and Shift ruler-tick snapping all count from that zero point:
the view's active artboard reaches the tools through `ViewInfo` and
`ToolContext::ruler_origin`. Command coordinates stay absolute.
Tests: engine/tests/ruler_origin.rs (default mode, per-artboard origin
following its artboard, global origin apart, toggle and undo, save and
legacy files, out-of-range values), ui-egui/src/tests_ruler_origin.rs
(position fields and corner drag on the active artboard, menu label and
shortcut), tools/src/rulerguide.rs (guide readouts and tick snapping).
Tests written for the single global zero point now turn global rulers
on first. "Change to Artboard Rulers" is translated in every catalog.

In a rotated view the resize and rotate cursors were the ones for an
unturned view. With the view turned 90°, the right-middle handle of a
selection's bounding box shows at the middle of the box's bottom edge
and drags up and down, but its cursor was the left-right arrow. This
affected the Selection, Free Transform, Artboard, Slice Selection, Crop
Image, Perspective Grid and Perspective Selection tools, ruler guides,
and the spread handle of a freeform gradient.
Now each of these cursors turns with the view to the nearest 45°. The
Selection tool and the Perspective Selection tool turn the handle's
direction by the view's angle before they round it to a cursor.
ToolContext::view_angle reads the view's angle from the screen frame,
and Cursor::turned turns a resize or rotate cursor by it. The new
Cursor::rotate_about_in_view turns the pointer's direction from the
center by the view before it picks one of the rotate cursor's eight
directions. Cursor::rotate_about keeps its signature and behavior. At
0° every cursor is as it was.

A Selection tool marquee selected every object it touched, a Group
Selection marquee selected the anchors inside it, and E pressed during
the drag did nothing. Now E switches either marquee to selecting only
the objects that lie entirely inside it, measured by their geometric
bounds, and E pressed again switches it back. Each marquee starts in
the default mode.
- The Selection tool selects a group only when the whole group lies
inside. Group Selection selects the objects inside groups, each as a
whole object. Shift still toggles. Direct Selection does not take E.
- The ruler guides the marquee selects with the art are limited the same
way: an artboard guide is selected when its whole length lies inside,
and a canvas guide is not selected.
- Tools receive letter keys as ToolKey::Letter. While a tool is busy, the
desktop app sends it each press of a letter it claims, without Cmd,
Ctrl or Alt and without key repeats, and headless press_key sends a
claimed letter the same way. With nothing dragged, press_key {key: "e"}
still chooses the tool bound to E.

A ruler guide goes on the current layer (guide.add {layer}), shows,
hides, locks and is deleted with its layer, is listed in the Layers panel
as a row that selects it, and moves to another layer (guide.setLayer).
Guides on a hidden layer neither show nor snap; those on a locked layer
can't be picked.

- `Targets::align_rects` tells `snap_point_with` an axis lined up even when
nothing moved or Alignment Guides hide the line, so the "align" label stays.
- Free Transform's move offset is a measurement label (as the Selection
tool's), its scale/rotate readouts Transform Tools; slice move/resize
readouts follow Measurement Labels.
- Snap to Point (Smart Guides off) keeps the default look for moves too, as
for drawn points and guides.
- Test: guides dragged out of a ruler (#451) follow Snapping Tolerance,
Anchor/Path Labels and Measurement Labels; docs/mcp.md.

Color, Alignment Guides, Anchor/Path Labels, Measurement Labels,
Transform Tools, Object Highlighting and Snapping Tolerance are read:
- tools: `guides::GuideStyle` on `Targets` (`styled(cx)`) colours the
lines and labels and leaves them out when their option is off, the
snap itself unchanged; `ToolContext` gains the six fields and
`snap_tol()`, replacing the 5 px literal for every smart guide snap
(drawn points, moves, bounding-box handles, ruler guides, artboards,
reference points). The tools gate their `Overlay::Measure` readouts on
Measurement Labels (drawing, moving, ruler guides, artboards) or
Transform Tools (scaling, rotating, Free Transform, transform tools).
- engine: `with_tool_cx` fills them from `Prefs` (the colour parsed, magenta
as fallback); the colour's default is `#ff3dfc`, what the tools drew.
- ui-egui: the hover outline needs Object Highlighting and Smart Guides.
- Tests in tools (guides, select), engine (tests_prefs) and the canvas;
docs/mcp.md and ROADMAP.

Guides dragged out of a ruler did not snap at all (only Shift to the ruler's
ticks): they now go through the engine (`Session::ruler_guide`, a
`NewGuide` previewing `guide.add`, one undo step) and snap as a moved guide
does: with Smart Guides to the edges, centres (so the sides' midpoints) and
anchors of the art and of the artboards, labelled; with Smart Guides off,
View > Snap to Point pulls new and moved guides onto anchors. Moving art
with the Selection tool already snapped flush to artboard edges and centres
with Smart Guides on; a test now covers it.
Artboard guides: `Guide.artboard` holds an artboard id (written only when
set, so canvas guides save as before and older files open unchanged).
`guide.add {artboard}` makes one, `guide.list` reports it; a guide dragged
out of a ruler with the Artboard tool belongs to the active artboard. It is
drawn, picked and snapped to across its artboard only, moves with it
(`artboard.move`, a pure move in `artboard.setProps`, `artboard.rearrange`),
is copied with it (`artboard.duplicate`, Alt-drag copy) and deleted with it
(`artboard.delete`, the guide selection kept in step).
Guides as Layers rows with their own lock and hide (part d) stay open: ruler
guides are not layer nodes; Lock Guides locks them all, and Make Guides
paths are Layers rows already. Listed in the ROADMAP parity row.

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).
