Round a closed path the editing data's text document writes the end of
the type's range unwrapped, past the last segment (the start plus the
run), or wrapped the other way. The importer clamped it to the path's
end, so the type kept only the stretch from its start bracket to the
path's end and overflowed. Both brackets are now wrapped onto the loop
(non-finite values fall back to the start); an open path is clamped as
before.
The object's own path that then replaces the frame is written open,
ending on its start: such a path is now closed where its ends meet, so
the span is measured round the loop.
Hand-written tests: an unwrapped, a reversed and a negative range on a
closed circle, a range inside it, an exact full turn that fits a short
line, an open path still clamped, and a path ending on its start closed.
Highlight Alternate Glyphs (8689863f) flagged any glyph that isn't its
character's cmap glyph, so the joining forms Arabic and other complex
scripts always take (init, medi, fina, isol, rlig, ccmp and the Indic
required set) covered ordinary text in pink. A glyph is now an
alternate only when required shaping alone doesn't give it: the text is
laid out again with every optional feature off (liga, clig, calt and
the features its characters turn on) and each candidate glyph compared
by cluster. The pink boxes are measured once per text geometry, only
when the preference shows them.
A group of four clip groups, each a placed image larger than its
rounded-square mask: one Selection click selects the group, which
shows the four masks' outlines and no image rectangle, with a bounding
box and bounds equal to the union of the masks. The behaviour landed
in #2650 (part of #2422); this covers the grouped case.
A right-to-left paragraph in an Illustrator editing copy (key 33 of its
paragraph attributes) stores its alignment relative to its direction:
"left" lays the line out ending at the anchor and "right" starting there.
The importer read the alignment alone, so RTL point type opened shifted by
its own width (Arabic headings past the artboard edge, subtitles starting
where their title ends, a label over a QR code).
Checked locally against ~1,440 single-line point-type stories in a user's
own files (never committed): RTL + left ended at the anchor in 332 of 336,
RTL + right started there in 51 of 51; LTR and centred type unchanged.
Justified alignments keep their current mapping (too few samples).
The Curvature tool built its curve as a uniform Catmull-Rom: both handles of a
smooth point a sixth of the chord between its neighbours, the ends of an open
path without handles. Uneven spacing overshot or looped, a J or U from three
points bent sharply at the middle with straight legs, and the end segments
looked flat.
- `curvature_spline` (draw2.rs) makes each stretch of three points follow the
circle through them: a smooth point's tangent is that circle's
(`smooth_handles`), each handle `chord / (3 cos²(α/2))` long, α between
handle and chord capped at 90° (`arc_handle`). The ends of an open path
mirror their neighbour's tangent in their chord (`end_handle`). A turn
tighter than 30° (`TIGHT_TURN`) shortens its handles, so a narrow V comes to
a point. Degenerate points become corners. `path.curvature` and the rubber
band use it.
- `catmull_rom` is unchanged for the Pencil and Paintbrush fitting.
- `bend_last` (from: smooth), `curvature_move` on a smooth point, the point
`curvature_insert` adds on a straight segment, and `path.convertAnchor` to
smooth without x/y (`curvature_smooth`) use the same rule.
- `curvature_extend` gives the new end its end handle unless Alt-clicked
(`corner` param on `path.curvatureEdit`).
- Neighbours of a point dragged on an existing path keep their tangents (a
Pen-drawn shape isn't reshaped); the path being drawn re-curves throughout.
The drag threshold kept `last` at the press position until it was crossed, so
Space held when the move that crossed it came moved the anchor by the whole
distance since the press. `last` now follows the pointer while the threshold
swallows the moves, and the threshold is measured from a separate `pressed`.

General > Use Precise Cursors already worked and is saved with the other
preferences. This adds a `view.preciseCursors` command that toggles that same
preference, so it can be given a shortcut in Edit > Keyboard Shortcuts. It has
no default shortcut and no View menu item.
The comment in canvas.rs claimed Caps Lock gave precise cursors; nothing reads
Caps Lock (egui has no state for it), so it now describes what the code does.
Tests: for the tools whose own pointer the preference replaces (Pen, the anchor
tools, Curvature, Mesh, Eyedropper, Slice, Blend, Shape Builder) the pointer is
their own when off and a crosshair when on; every state of the Pen's pointer
turns into a crosshair; the preference round-trips through
to_json/apply_prefs; the command toggles it, updates the saved UI state, is
listed in the shortcut editor without a key and can be assigned one; switching
it creates no undo step and leaves the document saved; with system cursors the
glyph fallback is the system crosshair either way. The new label is translated
in the languages that claim complete menus.

Covers the Illustrator behaviour that a corner placed after a smooth anchor
has no handles, so the segment is shaped by the previous outgoing handle alone.
Co-Authored-By: Claude Sonnet 5.5 <[email protected]>
A press released within a few screen pixels is a click: the anchor stays a
corner with no handles, as in Illustrator, instead of getting near-zero
handles from a trembling hand. The threshold is in screen pixels, so it
does not change with zoom. It applies to new anchors, closing a path and
pulling a handle out of the last anchor.
