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.

//! File → Export → Save for Web (Legacy) (`saveForWeb`, Ctrl/Cmd+Alt+Shift+S): the art previewed
|
||
//! as the web image Save writes, beside the original (Original, Optimized, 2-Up and 4-Up views,
|
||
//! each with its file size and download time), and the settings: format (GIF, JPEG, PNG-8,
|
||
//! PNG-24), colour reduction, colours, dither, transparency and matte, interlacing, web snap,
|
||
//! lossy, JPEG quality, the colour table (lock, map to transparent, web shift, sort), image size
|
||
//! and anti-aliasing, Clip to Artboard, sRGB, metadata, slices and HTML output, and presets.
|
||
//!
|
||
//! Fields are the `document.exportForWeb` settings (`webExport.settings` gives them; set one with
|
||
//! `ui.dialog.set`, or `preset` to load a preset), plus the dialog's own: `__view` (`original`,
|
||
//! `optimized`, `2up`, `4up`), `__zoom` (`fit` or a percentage), `__kbps` (connection speed),
|
||
//! `__color` (the colour table's selected colour, by source), `__presetName` (shown while saving a
|
||
//! preset) and `__hasSlices`. Save… remembers
|
||
//! the settings and writes the files (`file.saveForWeb`); Done only remembers them; Preview in
|
||
//! Browser opens the HTML page (`file.saveForWeb.browser`). The previews are what Save writes:
|
||
//! [`webexport::preview_image`], decoded back, cached until the art or a setting changes.
