* #1500: shape fills keep gradients and transparency (model, DOCX read/write) A shape's, text box's and canvas's fill is now a `Fill` (solid with transparency, or a gradient kept as the file states it) instead of one opaque colour, so gradients and transparency survive opening and saving. - doc: `fill::Fill`/`Gradient` with sanitizing for hostile input; `.json` keeps writing opaque solid fills as `[r,g,b]` and reads both forms; `ShapeExtra::outline_fill` keeps an outline gradient. - docx read: `a:solidFill` with `a:alpha`, `a:gradFill` (stops, `a:lin`, `a:path`/`fillToRect`, `tileRect`, `rotWithShape`, `flip`), theme fill styles through `a:fillRef` 1-999/1001+ with `phClr`, `a:grpFill`, `satMod`, outline gradients, VML `v:fill` gradients and opacity, canvas backgrounds. - docx write: `a:solidFill` + `a:alpha`, `a:gradFill` as read. - engine/docbin/layout: call sites; drawing still uses the main colour (next commit draws gradients). Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * #1500: draw shape gradients and transparency (layout, render, PDF) - layout: WordArt's paint becomes a shared `display::Paint` (solid, linear, radial); `paint_for` lays a fill over the shape's frame (linear at its angle, `scaled` honoured; path gradients circular from their focus to the farthest corner). Shapes, freeforms and canvas backgrounds use it. - render: one `set_paint` for shapes, paths and WordArt; radial gradients; soft edges fade the real fill. - pdf: axial and radial shadings with per-stop opacity. - Review fixes: nested groups without a fill pass theirs on to `a:grpFill`, text-box contents don't take a group's fill, `phClr` transparency only on `phClr` colours, VML focus ends consistent and opacity clamped, `rotWithShape`/`scaled` written only when set, Shape Outline clears an outline gradient, shared stop sanitizing. - docs: file-format, layout parity, gaps #1, roadmap progress log. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * #1500: shape.fill sets transparency and gradients on every selected shape - shape.fill (now cmd/shape_fill.rs) takes {"color", "transparency"?} or {"gradient": {stops, type, angle, focus, rotateWithShape}}; a colour alone keeps the transparency; values are sanitized; applies to every selected shape, text box and canvas as one undo step. - Formatting (shape.fill, shape.effects) keeps a Shift+click multi-selection, as in Word. - view.formatShapePane toggles the Format Shape pane. - Session::undo_mark/merge_undo_since: a pane drag that applies as it goes undoes in one step. - Helpers for the pane: params(fill), stop add/remove/move, directions, variations and presets (variation and preset colours provisional until compared with Word). - Catalog: Shape Fill Gradient, Format Shape Pane. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * #1500: Shape Fill › Gradient and the Format Shape pane - Shape Fill › Gradient: No Gradient, Light and Dark Variations of the shape's colour, More Gradients… (opens the pane). - Format Shape pane (right): No fill / Solid fill (colour, transparency) / Gradient fill (presets, type, direction, angle, stops bar with add/remove/drag and arrow keys, per-stop colour, position, transparency, rotate with shape). Drags preview live, one undo step. - Right-click › Format Shape… on shapes, text boxes and canvases. - Gradient swatches have accessible names; new labels translated (own wording, clean room).

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * #1500: review fixes for the shape fill ribbon controls - Gradient variations are built from the colour the shown variation came from, so picking variations in turn, or No Gradient, doesn't drift the colour. - A drag's undo mark is forgotten while the Format Shape pane is closed (a stale mark could merge later undo steps). - Dragging on the stops bar away from a handle no longer moves the selected stop; the arrow keys are taken by the bar (no focus moves or shape nudges). - Direction and Type changes keep a linear gradient's "scaled" and an imported tile rectangle; only a corner direction sets its tile. - Colour modifiers (lumMod, lumOff, tint, shade, satMod) live on Rgb in the doc crate, shared by the DOCX reader and the gradient builders. - Previews build their stop list once per swatch, not per vertex. - Translations for the pane's hint, direction and preset names. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * #1500: adapt to main: caret contrast samples gradient fills; upstream tests use Fill/Paint - Paint::at gives a paint's colour and opacity at a point; the caret's background sampling (#299) uses it for shape fills, now gradients or transparent, and the Format Shape previews use it too. - Upstream tests (#886 shapes survive saving, render) build fills as Fill/Paint. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * #1500: adapt to main after the rebase: VML presets, rounded corners, new catalogs - vml_fill takes the shape's shapetype: a VML preset shape (#1377) takes its fill, opacity and gradient from its shapetype when it states none of its own, as it already took its colour. - Rounded-rectangle corners (#1476) and the gradient paints meet in render, PDF and the caret's background sampling; ShapeExtra keeps both `corner` and `outline_fill`. - Tests that landed on main since build fills as Fill/Paint (VML presets, cover pages, VML freeforms, path arrowheads, PDF and render shapes). - The 40 Shape Fill / Format Shape strings in the hr, ko, sv and vi catalogs, which main gained since.
