M2.9: hexagon orientation no longer depends on atan2 rounding
The Shaper fits a hexagon's rotation by scoring 0, 90, 180 and 270
degrees, but a hexagon at 180 is the one at 0 (and 270 the one at 90):
those pairs score the same up to rounding, so the platform's atan2 picked
between them. FreeBSD's libm gave 270 where Linux gives 90, failing
tilted_rectangles_ellipses_and_hexagons_snap_to_their_angle_steps on the
FreeBSD build+test job. Candidates a whole number of periods from an
earlier one are now dropped. A new test reproduces the flip on Linux
with the old code (180 instead of 0 at tilt -9).

Cargo.toml Rename DrawCraft → VectorCraft: crates (vectorcraft-*), apps, binaries, types, env vars, docs, examples (.vectorcraft); old .drawcraft files and preferences still load. Fix: text bounds exact after opening a file; selection no longer marks a document modified (dirty = content differs from the saved document). Screenshots and renders regenerated. 2026-10-01 14:30:09 -04:00
