The shaper lets one call grow to 256 glyphs per input character, as an
embedded font's substitutions decide, and every glyph was then copied out.
Items longer than 1 KiB are now shaped in pieces (cut at a space where one
is near, never before a combining mark or after a joiner), each with the
rest of the paragraph as context and the item's script, and a piece that
expands past 32 glyphs per character falls back to one glyph per character
from the cmap.
* Animations: index morph matching and timeline lookups by shape
Morph pairing searched every shape of the next slide for each shape of the
current one, four times over, rebuilding shape text inside each comparison.
Timeline state looked up a shape's effects, paragraph owner and base colour
by scanning every effect, group and colour on the slide, once per shape and
paragraph drawn. Both are now indexed once, keeping the same match order.
* Animations: drop wall-clock bounds from the large morph and paragraph tests
On a loaded runner a ten-second bound can fail after every functional
assertion passed. The inputs stay large enough that a quadratic regression
hangs the test instead.

Review of #1693 found that cast_effects built the picture content that a shadow,
a glow and a reflection are drawn from without converting a tiled fill to
points, so inside a scaled group the reflection of a tiled picture showed
child-space tiles while its face showed the right ones.
The content now goes through paint::tiled_picture_per_point with per_point_xy,
as the face does.
Test: a tiled picture's reflection in groups scaled 0.25, 1600 and 2x0.5 shows
the same colours as in an unscaled group; it fails without the change.

Review of #1693 found two more places that drew a tiled picture fill in the
shape's own (child-space) units inside a scaled group.
A group nested in a scaled group stored its own tiled fill unconverted, so the
members that take it (grpFill) got oversized tiles. The owning group now
converts the fill with per_point_xy when it stores it, so inheriting members,
directly or through a chain of grpFill groups, get the converted tile.
A picture shape (p:pic) whose blip fill is a tile passed its own fill straight
to paint::picture. It now goes through paint::tiled_picture_per_point, which
tiled_per_point also uses.
Tests: a group's tile passed to its members and a picture shape's own tile, each
in outer groups scaled 1, 0.25, 1600 and 2x0.5; both fail without the change.
Docs: the Picture and texture fill checklist row is re-assessed (remains P) with
its status line and revision history, and the ROADMAP progress log row mentions
both cases.

A tiled picture fill (a:blipFill with a:tile) was sized in the shape's own
units. Inside a group whose child space differs from its box (old decks write
child spaces ~1800 times smaller) one tile covered hundreds of boxes, so the
fill showed a single flat texel instead of the texture.
PowerPoint's own PNG export of a synthetic probe deck shows the tile keeps its
size, offset, anchor and mirroring in slide points whatever the group's scale,
uniform or stretched unevenly, nested or flipped. The tile is now converted
from points to shape units per axis (Renderer::per_point_xy, paint::
tiled_per_point), and snapped to whole device pixels per axis.
Tiles with rotWithShape="0" are drawn in device pixels and were sized in
pixels, ignoring the zoom (even outside groups); they are now sized to pixels
first.
Tests: a tile in groups of seven scales (uniform and uneven, wide and tall
tile), and an upright tile in a turned shape at zoom 1 and 2.

- Use render_frame with timeline.steps() and t = 0.0 so the previous slide
is rendered in its final completed state during transition preview.
- Pass duration: 1000 integer ms in test to explicitly test the requested duration.

- When Preview is clicked on the Transitions ribbon, initialize Show with
start_transition_preview from the prior slide into the selected slide
(or from black for slide 0).
- If tr.old is unset for a non-part transition with tr.from, render the
previous slide texture on the first frame so the transition blends cleanly.
- Indicate active playback on the Preview button while previewing.
- Regression tests for transitions from previous slide and from black on slide 0.
Main fixed the PDF font fixture independently (9005839), so that half
of this branch is dropped in favour of main's version; the language
dialog label fix remains.
