Type is drawn as its glyph outlines under a geometry effect, in EMF and
WMF export, in DXF export when it is written as outlines, through
Flatten Transparency with Convert All Text to Outlines, and inside an
envelope. Those outlines differed from the type the canvas draws in
four ways. They had no underline or strikethrough bars. A character
stroke on scaled type kept its unscaled weight. An unplaced gradient was
fitted to the glyphs it painted instead of the layout box. A run's
pattern tiles stayed in document space instead of scaling and turning
with the type. A group's or layer's own fills and strokes also painted
the glyphs of the type in it without the bars.
The outlines now include each run's underline and strikethrough bars,
as the canvas has drawn them since #850. Each run's path is made in
text space with its unplaced gradients fixed to the layout box, then
placed by the type's transform, which also scales its stroke weight
and dashes and transforms its pattern tiles. The type's own fills and
strokes have their unplaced gradients fixed to the bounding box of the
layout box in the document, where the canvas fits them.
Geometry effects that move or scale the outlines move and scale the
type's gradients with them: the type's own effects, also inside an
envelope and after Flatten Transparency has converted the type to
outlines, and the effects of a group, symbol instance or envelope that
holds the type. outline_text marks its group with a new node field,
type_outlines, which is saved with the document. reshape_leaves maps
the placed gradients in each marked group through the map that takes
the group's bounds before the effects onto its bounds after them. A
scale out of proportion stretches a radial gradient into an ellipse
and turns the isolines of a diagonal linear gradient, as it does on
type scaled by its own transform. Placed gradients outside those
groups stay where they are.
Same treatment as the branch's `as_chunks` commit (Rust 1.99's
`chunks_exact_to_as_chunks` lint) for the flattener's coverage pass, the
CMYK ink compositor, the Flattener Preview highlight and four test helpers.

effect.expandAppearance now expands the whole appearance: each visible fill becomes a
path of its own and each stroke its outline (a brushed stroke its brush art), grouped
in paint order under the object's id and transparency; geometry effects are baked and
raster effects become an embedded image (shadows below the art, blur/feather/inner glow
replacing it). Type with effects or its own fills is outlined, and a group's or layer's
own fills and strokes are expanded among its members. The command is enabled whenever
an appearance isn't basic. Builds on bake_leaf (effects::expand_leaf / expand_art) and
shares the raster-effect image code with PDF export.
