The wheel did nothing over numeric fields. As in Illustrator, once a numeric
field has the focus, turning the wheel over it steps its value like Up/Down:
a notch a step, Shift ten, Ctrl/Cmd a tenth, applied at once with the new value
selected.
- widgets::step_value (was step_with_arrows) reads the arrows and the wheel
through one path for num_field, plain/mixed fields and the spin fields built
on them (panels, the Control bar, dialogs, the Font Size and Leading combo
boxes), and now opt_field (Stroke dash/gap) too. Trackpad and fine-wheel
points add up to notches; the rest carries to the next turn.
- While the pointer is over the focused field the panel under it doesn't
scroll; an unfocused field, or the pointer anywhere else, leaves the wheel to
the panel and the canvas as before.
- The dialogs' and preferences' egui drag values become the same recessed
number fields (widgets::range_field: clamped to their range, rounded to their
precision), so they type, step and scroll like every other numeric field.
- Headless tests for the wheel (units, modifiers, points, focus and pointer),
and for the panel scrolling or not; docs/control-protocol.md and ROADMAP.
