The Parametric Shape tool's center and the Slice tool's corners snapped
with Smart Guides to the bounds of the art only, so View › Snap to Glyph
had no effect on them, and neither did the anchors and segments of
paths that the other drawing tools snap to. The point dragged out from a
Parametric Shape's center did not snap at all, and neither tool showed
Smart Guides while hovering before a press.
Both tools now snap through the drawing tools' shared snapping
(DrawSnap). A Parametric Shape's center (from a drag or a double-click),
the point dragged out from it, and a slice's corners land on glyph
guides and on path anchors and segments. The guides show while hovering
and during the drag. When a ruler guide then takes a slice corner, the
Smart Guides are no longer shown. A click with the Parametric Shape tool
still draws nothing when its center snaps a few pixels from the pointer.

Control bar > Snapping > Pixel Snapping Options... opens a dialog with
three checkboxes: Snap to Pixel While Drawing, While Moving and While
Scaling. OK sets them; Cancel leaves them as they were. While View >
Snap to Pixel is off, the dialog notes that the options take effect once
it is on.
- view.snapToPixel.options {drawing?, moving?, scaling?} reads and sets
them. They are kept in the preferences as the pixelSnap group, all on
by default, so turning Snap to Pixel on behaves as before. An unknown
key or a value that is not a boolean is refused and changes nothing.
The command has a parameter schema, which raises the API level to 4.
- Drawing covers points the drawing tools place, the Knife's straight
cut, the Measure tool and the rulers' origin. Moving covers Selection
and Direct Selection moves, ruler guides, artboard moves and the
Rotate, Reflect and Shear tools' drags. Scaling covers bounding-box,
Free Transform, artboard and slice handles and the Scale tool's drag.
An edit whose option is off snaps as it does with Snap to Pixel off.
- Align New Objects to Pixel Grid and the objects' pixel-aligned
property do not depend on these options.

Ruler guides were a list kept beside the layers. Each guide is now an
object of its layer or sublayer, always directly in it and above the
layer's art. These behave as on main:
- Guides draw on screen only. Exports (SVG, PDF, PNG, PSD), Fit All,
Select All, the art bounds, clicks and marquees, and a layer's
Pathfinder and Transform effects leave them out. The Layers panel
lists them as guide rows of their layer, the highest guide.list
index first.
- Deleting a layer deletes its guides, and merging layers keeps their
guides in the merged layer.
- The guide commands number guides as guide.list does, in the order
they were made.
New: each guide takes an id from the document's object ids. An object
command given a guide's id fails with an error, and node.move cannot
put a guide into a group or out of its layers. A guide made while an
opacity mask, a symbol or a pattern is edited moves to the top
visible, unlocked layer when editing ends.
File format: native files still save the guides in the document's
guides list, in every file version, so older builds read them. Each
entry may now also carry the guide's id, name, locked and hidden
flags; older builds ignore those fields. Opening a file puts each
saved guide on its layer (on the top visible, unlocked layer when the
file names none or a layer it does not have), and each saved guide
counts against the object limit for opening a file. A ruler guide node
that a file holds below a layer's art moves up to the layer's guides,
and one anywhere else (in a group or another object, beside the
layers, or in a symbol) is removed. Ruler guides read from an .ai file
become guide objects on the layer they were on, numbered in the order
the file lists them.
Dragging a user slice's edge or corner handle with the Slice Selection
tool never snapped, while drawing a slice with the Slice tool snaps to
the grid, to whole pixels, to the art and to the ruler guides.
The handle drag now gathers its targets when the handle is pressed and
snaps what the handle moves through PointSnap::snap_scale, as the
Selection tool's bounding-box handles do: to the nearest gridline with
Snap to Grid, to whole pixels with Snap to Pixel, to the art and the
artboards with Smart Guides, and with Smart Guides off to the art's
anchors and the ruler guides with Snap to Point. Then a shown, unlocked
ruler guide within 5 px moves the side or corner onto it, as the Slice
tool moves a drawn slice's corner onto a guide. Shift still keeps the
proportions, and Alt still resizes about the center.
Docs: docs/target-app-parity.md.
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 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.

The Slice tool (Shift+K) drags out a user slice (Shift square, Alt from the
centre, snapping to ruler guides) as one undo step through
object.slice.create. The Slice Selection tool selects slices (Shift
toggles, object.slice.select), moves them (object.slice.move; object
slices move their objects), resizes a user slice by its handles
(object.slice.setRect), opens Slice Options on a double click and deletes
with Delete (object.slice.delete). Hidden or locked slices can't be
picked. Both tools have cursors drawn in code.
