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.

- 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.
