- Inline IME composition: egui Preedit events become a composition held in the text edit
session (`TextEdit.preedit`), shown inline at the caret with an underline and the IME cursor,
reflowing the text; the document only gets the committed text (`text.edit.insert`). Composing
over a selection replaces it; moving the caret or ending the edit drops an uncommitted
composition. The IME candidate window follows the cursor inside the composition.
New command `text.edit.preedit {text, cursor?}`; `text.edit.selection` reports it.
- Variable fonts: faces read their fvar axes (tag, name, range, default, hidden) and named
instances. Named instances are offered as styles and resolve in `find`; a style name with no
instance implies weight/italic/slant on the axes and optical size follows the font size.
Per-run custom axis values (`TextStyle.variations`, serde default, omitted when empty) are applied
in HarfRust shaping (ShaperInstance) and skrifa outlines/advances (cached per coordinates).
PDF export outlines non-default instances instead of embedding the default one.
- Commands/props: `fontVariations` / `variationSettings` props (whole layer or start..end),
`text.setVariations {variations, replace?}` (merges; edited range while editing),
`text.fonts {family, style?, axes: true}`; `node.get` and copy/paste properties carry the axes.
Picking a named style (Bold/Italic toggles, weight steps, fontStyle/fontWeight) drops custom
wght/ital/slnt values and keeps the others.
- Type settings ▸ Variable tab for variable fonts: a slider (default tick, double-click to reset)
and a field per visible axis, "Mixed" across differing styles, live drag as one undo step,
"Reset to style". Long style/family names stay on one line with an ellipsis and a tooltip.
- Tests: variable font shaping/outlines/clamping/instances (skipped without a variable font),
serde backward compatibility, preedit lifecycle and undo, variation commands/props/undo/junk;
junk sweeps extended with variation and preedit params.
