A Selection tool press within reach of an anchor or the centre grabs the
object by that point, but the drag threshold was measured from that point
instead of from the press. A press 3-6 px from it was already past the
threshold, so the first pointer wobble started a move and jumped the
object by the offset. The threshold now counts from where the pointer
went down; a real drag still moves the object by the grabbed point.
A variable font's COLR layers follow its instance, a colour glyph turns with type on a path, and the canvas draws an SVG glyph's art in its own colours and the type's fill.
The editing data writes a gradient mesh as its patches, each with its
place in the grid (`/P`) and the grid's size (`/Size`); the importer
read each patch as a mesh of its own, in a group, so moving a mesh
point tore a patch away and left a hole, and a patch with anchors on
its edges was cut into cells on its own.
The patches are now placed by `/P` in the `/Size` grid and joined at
the corners they share into one GradientMesh. Which index of `/P` runs
along the columns is taken from the one under which the shared corners
meet. Where an edge bends through anchors, a mesh line runs through the
whole row or column of patches there, each patch cut at the same place,
so every cell keeps single-cubic edges. A mesh whose patches don't say
where they are reads as before; one whose patches fill the grid but
don't join up reads as before with a warning. Sizes and lines are
capped; non-finite values fall back.
Hand-written tests: a 2 x 2 grid as one mesh with the old patches'
colours, a moved inner point shared by its four cells, an anchor on a
shared edge adding a line through the mesh, a collapsed patch with
finite values, and unplaced or unjoined patches staying separate.
The colour glyph cache keyed the text's colours by their 8-bit RGB look, so a fill that only looked like an earlier one (a grey and the same RGB grey, a spot colour and its process match) took that one's colour, and its separations. It now keys them exactly.
A system fallback search can add no new face because another lookup loaded it
first. Re-read the loaded faces regardless of the search's return value, so
concurrent first use does not produce a missing glyph and different advances.
Add an isolated generated-font regression with simultaneous cold lookups.
The original code missed 14 of 16 lookups; the fixed regression passed twenty
runs. Both previously failing Ruby tests pass unchanged.
Validation: Rust 1.98.1 cargo xtask ci, all 10 gates passed; workspace tests
9,635 passed, 0 failed, 14 ignored. Default Rust toolchain unchanged.
