The snap toggle was a checkbox with the word "Snap" next to Fit, and
the vector art tab had its own "Grid" button for the same idea. Both
now share one square icon button, so snapping looks and works the
same wherever it exists.
- SnapToggle is a square toggle button with a magnet icon and no
text. It lights up blue when snapping is on, like the other toggle
buttons.
- The magnet is drawn with cubic curves instead of arcs, because the
Pixi SVG parser draws arcs as jagged edges.
- The vector art tab drops its Grid button and uses the same
SnapToggle. It still snaps to 8 px, the graph tabs to 24 px.
- SnapToggle accepts anything with setSnapping(on). The vector art
canvas method is renamed from setSnap to setSnapping for that.
- Every tab exposes the button as __gm.<tab>.snapButton(). Modules
06, 26 and 36 click through that hook instead of the label "Snap"
plus 30 px.
Tests:
- ./check.sh: 129 files, 1903 tests (was 128 / 1897)
- 3 new tests in tests/editor/snap-toggle.test.ts, 3 in the icon tests
- GM_STEPS=1-6,26,36,47 fresh: ALL PASSED, 346 checks
- GM_STEPS=47: ALL PASSED, 32 checks (was 29)
- Counter-checks: toggle not switching its target fails 2 unit
tests, the canvas ignoring the switch fails module 47
- Check total 1188 in README and wiki is computed (1184 + 4), the
full run is left to CI
