convert, run --save and run --export picked the format from the output
extension and fell back to native .deckcraft bytes for any extension
they didn't know, so out.odp, out.gif, out.svg and out.outline were
zips with exit status 0. They now fail before writing anything, with
the extension and the supported ones in the error.
Make the slide show behave like PowerPoint for interactive decks.
- Hit testing resolves the topmost visible shape under the pointer.
Non-interactive shapes block shapes beneath them; the hand cursor
shows only over interactive shapes.
- Click-triggered animations (interactive sequences) play on shape
click, repeat after their last step, and apply in click order so
cycling "score ring" shapes work.
- Each slide keeps its own progress: returning to a slide through a
link or Back restores hidden shapes and animation state.
- A shape with a link and an animation follows the link immediately;
its animation clock only runs while the slide is shown and resumes
with the remaining time on return.
- With advance-on-click off, background clicks still play animation
steps but never change slide.
- A click on a playing step completes it at once.
Docs (gaps, animation and slide show parity, roadmap) are updated.

The row count came from 1/(1.5*rh) - the row spacing alone - and
ignored how far a settled hexagon actually reaches. On a 16:9 slide
the eleven rows stopped at ~75% of the height: from t~0.9, when every
cell has settled, the bottom quarter was plain black until the t=1
endpoint snapped to the full new slide.
The count now derives from the real geometry: rows sit 0.866*rh apart
and the flat bottom zone of a settled hexagon reaches 0.289*rh past
its centre, so counting to the flat-zone reach covers the slide for
every aspect ratio - counting to the vertex reach still left small
V-notches of black above the bottom edge on about a third of them
(US Letter, square, ...). 16:9 gains four rows (15, was 11), 4:3
seven (20, was 13).
Tests: at t=0.99, when every cell is settled and the seams are nearly
closed, a 0.02-step grid over the slide must sit inside settled
incoming cells (padded 1% past the hairline seams) on five aspect
ratios including US Letter and square. Fails on the old count at
(0.2, 0.74); before/after frames rendered with render-transition.
Every colour menu ends with Eyedropper. Choosing it closes the menu; the pointer is a
crosshair over the slide with the colour under it and its hex beside it, a click takes
the colour (slide.colorAt) and Esc, a right click or a click off the slide cancels.
The colour comes back through the menu that asked, which opens for a frame and returns
it as if its swatch had been clicked, so Shape Fill, Shape Outline, Font Color, the
Format pane and the other callers all apply it their own way without changes.
A read-only command, {slide?, x, y (slide units), scale?}: the slide is rendered and
the pixel at the point is returned as {color: "RRGGBB", alpha, x, y}. This is what the
Eyedropper takes, and what scripts and MCP use to read a colour off a slide. A point
outside the slide, a missing or non-numeric coordinate or an unknown slide is an error.
Progress log entry for the wild-case rendering fixes; "Bevel and 3-D
rotation" moves from missing to partial (approximate bevels, cameras and
face lighting; no extrusion, rigs or 3-D pane); gap estimate narrowed.

A shape with scene3d and sp3d but no bevelT was drawn in its flat fill
colour. PowerPoint lights the front face from the light rig whether or
not there is a bevel, so a plain 3-D rotated rectangle is lighter than
its fill. Model the face with the same threePt approximation as the
bevel (no rim), for solid fills.
Wild 3-D slides: s8 6.35 -> 4.26, s9 19.74 -> 17.68. Corpus unchanged
except lo tdf114848 s4 2.13 -> 1.94.

A shape seen through a 3-D camera preset (isometric, perspective...) or
turned with a:camera/a:rot drew flat and front-on. PowerPoint turns the
shape's plane in space and projects it. Fitted black-box to its exports
(a picture with coloured corner markers under every preset and several
rotations; every fit within half a point on a 100 x 75 pt shape): points
about the centre are turned Rz(-rev) Rx(lat) Ry(lon), perspective cameras
then dividing by D / (D - z) with D about 5-16 shape sizes; a:rot turns
the other way about the horizontal and vertical axes. DeckCraft now draws
the shape under the affine transform that best fits its turned corners:
exact for orthographic cameras, within 2% of the size for perspective
ones (an affine map can't foreshorten). Oblique cameras leave a flat
shape as it is; depth (extrusion) is not drawn.
Wild synthetic set: camera presets 15.02 -> 6.35, 3-D picture styles
16.00 -> 7.72, extruded cameras 21.41 -> 19.74.

- The magnetic disk's and drum's end ellipses were half the size of
PowerPoint's: ECMA-376 makes them h/6 high (disk) and w/6 across
(drum); measured on PowerPoint's outlines.
- The moon's inner edge was a half ellipse of the box's height; the
standard's is an arc of a larger ellipse through the right corners and
(adj * w, middle) whose centre lies right of that point (radius g18w
across, dy1 down), and so it is fuller. Text rectangle from the standard
too.
Wild synthetic set: preset galleries 3.76 -> 3.47, 3.45 -> 3.21,
4.31 -> 4.00 and others slightly.

A reflection on a picture (PowerPoint's "reflected" picture styles) drew
nothing: the reflection painted the shape's fill, and a picture has none.
It now mirrors the picture itself, clipped to its outline, under the same
fade.
Wild synthetic set: picture effects slide 16.77 -> 16.00 (the rest is
3-D camera rotation, not modelled).

A shape's picture fill marked not to rotate with the shape turned and
flipped with it (rotWithShape was neither kept nor written: always 1).
PowerPoint keeps such a picture upright, stretched (or tiled) over the
box the rotated shape covers on the slide and clipped to the shape. Now
read, written (PictureFill::upright) and drawn so.
Wild synthetic set: picture fills on rotated/flipped shapes 12.89 ->
3.87.

Five-, six-, seven- and ten-pointed stars used their own normalisation
and came out narrower or shifted against PowerPoint's. ECMA-376 places a
star's points on an ellipse around (hc, vc * vf) with radii half the box
times hf / vf (star5 1.05146 / 1.10557, star6 1.15470, star7 1.02572 /
1.05210, star10 1.05146), so the points touch the box's edges; now done
for all stars (checked exactly against PowerPoint's outlines at three
sizes and inner-radius adjusts).
Wild synthetic set: star galleries 4.08 -> 3.76, 3.77 -> 3.45,
4.62 -> 4.31 and the adjust galleries slightly.

An outline naming no join was always rounded. PowerPoint rounds most
presets but mitres some by default: classified per preset by comparing
its export (8 pt outline, no join) with round- and miter-joined renders:
the plus, right/up/down block arrows (not the left one), chevrons, stars
from five points up, the equation shapes, curved ribbons and the action
buttons. Miter joins also take PowerPoint's default limit of 8 widths
(kurbo's default was 4), so sharp star points no longer bevel off.
Wild synthetic set: joins slide 0.43 -> 0.21, outline-on-pattern slide
3.95 -> 3.76, preset galleries slightly better.

A gradient fill marked not to rotate with its shape turned and flipped
with it anyway. PowerPoint lays such a gradient out upright, over the box
the rotated or flipped shape covers on the slide (a 90 degree gradient on
a quarter-turned triangle still runs top to bottom). Linear and radial
gradients now do; rect and outline path gradients still follow the shape.
Wild synthetic set: gradients on rotated/flipped shapes 5.48 -> 1.34,
gradient angles slide 6.75 -> 1.95.

The shadow of a picture is the picture recoloured to the shadow colour,
but drawing the picture left its pixel-space transform set, so the
recolouring rectangle (sized in points) covered only part of a picture
whose bitmap is bigger than it is shown: a 400 px photo at 240 pt cast a
shadow of its top-left corner only. The shape's transform is restored
before recolouring.
Wild synthetic set: framed pictures with shadows 7.67 -> 5.95, rotated
picture with a shadow 10.67 -> 10.07.
