Each outline is our own construction in crates/geom/src/preset/extra.rs,
fitted black-box against PowerPoint renders of synthetic probe decks at
default, changed and extreme adjust values and several aspect ratios
(outline within ~1pt on 300-480pt shapes). Tests cover catalog presence,
hostile sizes/adjusts and measured outline points.

* Text warps: draw WordArt prstTxWarp presets, round-trip their adjusts
All 40 DrawingML text-warp presets now render instead of drawing flat text.
A warp is a list of bands over the shape's text rectangle (insets ignored):
fill bands stretch the ink of their lines between a top and a bottom guide
(positions by arc length, one horizontal scale for the whole text), follow
bands (arch, circle, button) set lines at natural size along an ellipse arc,
lines stacking outwards on parallel curves, with no wrapping. Lines are
shared over multi-band presets in order (ceil(n/k) per band).
The guide curves were fitted to PowerPoint renders of synthetic decks of
"I" bars (black-box observation, defaults and changed adjusts, 1-3 lines);
most presets match within about a point on a 420 x 200 pt box.
- geom: warp module (guides, presets, band mapping) with unit tests
- render: glyph outlines and underlines flattened, subdivided and mapped
- text: follow warps lay out without wrapping
- model/pptx: BodyProps.warp_adj read from and written to prstTxWarp/avLst

* Text warps: bands with fewer lines keep the fuller band's text height
Multi-band fill warps (Deflate-Inflate, Button Pour) map a box as tall as
the tallest band's ink onto every band, centred on the band's own ink, as
PowerPoint does: a band holding one line next to a band of two keeps the
line at the same size instead of stretching it over the whole band.

* Morph: a changed geometry morphs its outline (a circle turns into a star)
Paired shapes that differ only in geometry (another preset, other adjust
values, a custom path) and fill colour no longer cross-fade: one shape moves
and its outline turns from the old geometry into the new one.
- geom::morph aligns two outlines the way manim does: the same number of
contours, the same number of cubic curves per contour pair, then every
point moves in a straight line. Closed contours are turned and reversed so
the points travel least (a triangle does not twist into a circle), extra
points go to the longest curves, and a sub-path without partner grows out
of (or shrinks into) a point, so a cube's faces appear and a donut's hole
closes. Fill mode, outline and fill rule switch at the midpoint.
- anim::morph_frame lists such shapes in MorphFrame::paths; the renderer
draws them with the morphed geometry (PathMorph, a new render_blend
argument next to TextMorph).
Ported from the path morph in alexplain (MIT, same author).

* Morph: differing looks of an outline cross-fade instead of switching
When a sub-path pair differs in fill mode, outline or fill rule, the two
looks no longer switch at the midpoint. A fill or outline only one side has
fades out (or in), so a filled shape turning into a line loses its fill
gradually. When both fill, the even-odd side lies opaque underneath and the
other fades over it, so a donut's hole fills smoothly while it shrinks.
