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.

A default export is 2 pixels per point. Without a resolution, Preview
treats those pixels as 72 dpi and the picture opens at twice the slide's
size. PNG pHYs and JPEG JFIF density now say scale times 72, so the
default is 144 dpi. Screenshots stay untagged.

DrawCurve, DrawClosedCurve and FillClosedCurve (GDI+ cardinal splines, the
smoothed lines of charts and freehand shapes) draw as cubic Béziers with
the record's tension, offset and segment count; FillRegion fills the region
object's area. These records were skipped, so the shapes were missing.

Radar and filled radar charts are drawn polar: spokes per category,
polygon gridlines and value labels up the first spoke. Stock charts
draw high-low lines with close dashes, or up/down bars between open
and close, and are saved as c:stockChart (hiLowLines, upDownBars)
instead of a line chart; c:upDownBars is read, and chart.options takes
upDownBars. New stock charts start as high-low-close and new combo
charts as columns with a line.

Read the regionMap chartEx layout as a RegionMap chart (regions and
their colour values), write the part back as read while unchanged, and
when edited rebuild it with the original geography (projection, culture
and cached boundaries) carried over. With no map data in the repo, the
renderer draws each region as a value-coloured tile with a colour scale
and a note that the map itself is not drawn.

sp3d extrusionH (with extrusionClr, srgb or scheme) under a camera that
turns the shape now draws the shape's sides: its outline swept from the
back face to the front along the camera's view of the depth axis, in the
side colour shaded, before the face. camera::project3 projects points
off the shape's plane.
Read, keep and write every cx:lvl of a chartEx category dimension,
build a category tree from runs of parent labels, and draw treemaps as
nested squarified groups with banners and sunbursts as one ring per
level. Box & whisker honours quartileMethod="inclusive" (QUARTILE.INC)
on import, render, save and the chart.options command.

Histograms and Paretos bin their observations (bin count, bin width or
Scott's rule) and draw as touching columns, a Pareto with its cumulative
line on a percentage axis. Box and whisker charts draw exclusive-quartile
boxes, 1.5 IQR whiskers, means and outliers per category group.
Edited and new Office 2016 charts are written as chartEx parts from the
model (with the plain-chart fallback), so a waterfall stays a waterfall.
The chart menus list all seven types, and chart.options sets bins and
waterfall totals.

An owned corpus of those element kinds survives open, save and reopen.
Paragraph default run properties, including a link, and action sounds
were dropped on save, so import and export now keep them.
These Office 2016 charts were drawn as plain columns. Now:
- waterfall: bars float from the running total, total points
(cx:subtotals, now read into Chart.subtotals) stand on the axis and
reset it, increases/decreases/totals take accents 1-3 with a matching
legend, and connectors join each bar to the next;
- funnel: centred bars as wide as their value, category labels on the
left and values inside;
- treemap: squarified tiles in proportion to their value, labelled;
- sunburst: the innermost level as a ring with an open centre.

soak_tests.rs drives every non-file command with plausible and hostile
parameters over a ~100-slide deck, checking after each step that the
document validates, the selection is in range, the undo stack is bounded,
undo then redo restores the exact document, and every 100 steps that the
deck saves and reopens as .deckcraft and .pptx. Four seeds x 400 steps run
in CI (under a second); DECKCRAFT_SOAK_STEPS/SEED run it long.
The long soak found that a chart a few points wide panicked in f64::clamp
(label gutter min above max), and the render guard then blanked the whole
slide. chart.rs now uses a non-panicking clamp_soft for the gutters and the
zero line; a render test draws tiny charts next to a shape without the
guard.

INTERSECTCLIPRECT, EXCLUDECLIPRECT and EXTSELECTCLIPRGN limit what later records paint, including a region made of several rectangles. A rotated map stores the bounds of the clip rectangle.

Gradient tile rectangles were dropped on import. PowerPoint's "from
corner" radial presets depend on them: fillToRect puts the focus on a
corner and tileRect stretches the gradient's box a whole size past it, so
the circle is centred on that corner and reaches the far one. Without it
(after the two-point radial change) such fills washed out. A linear
gradient now spans its tile rectangle; a radial one ends on the circle
around it, with the focus still placed in the shape's own box (fitted to
PowerPoint's export of the corpus deck tdf114848: mean diff over the
filled box 0.77). Round-trips through pptx.
Wild synthetic set: tile-rect gradients 16.74 -> 2.48.

eaVert text was laid out exactly like vert: the whole text turned a quarter turn, so Japanese and
Chinese lay on their side. PowerPoint draws ideographs, kana, Hangul, full-width forms, CJK
punctuation, circled numbers and emoji upright, each turned back about the centre of its em box,
while Latin letters and digits stay on their side ("英字123も": 123 sideways). It keeps the glyphs'
horizontal forms (no vert alternates: "、" "「" are simply turned), which DeckCraft now matches.
Glyph runs carry an `upright` flag; the renderer turns each such glyph about its em box centre
(0.38 em above the baseline). w01-vertical s3 (eaVert) 9.70 -> 8.98, s6/s7 (eaVert rotated,
flipped, bulleted) 1.58 -> 1.45, 2.30 -> 1.76.

Every underline was a solid line 0.06 em thick at 0.12 em below the baseline, whatever a:rPr/@u
asked for. Underlines now sit at the font's own underline position and thickness (post table),
where PowerPoint draws them (Arial 96 pt: 10 px below the baseline, 7 px thick), and each style
is drawn as measured on PowerPoint's export: dbl two lines 0.55 thick spanning one thickness above
to the single line's bottom; heavy from one thickness above to 0.55 below; dotted dots and gaps one
thickness long; dashes three long with gaps of two; wavy a thin zigzag every 3.9 thicknesses. The
"words" style underlines spaces too, as PowerPoint draws it. Dashes and waves are new Deco line
kinds the renderer fills or strokes (warped text draws their boxes).
Underline slides: w14-xml s10 11.49 -> 10.43, s11 6.64 -> 4.06; w06-charfmt s3 9.66 -> 9.51,
s4 7.63 -> 7.44.

A combo chart (columns plus lines, often with the lines on a second value
axis) was read with each series' type but drawn as lines only, on one
scale, so a spend-and-clicks chart showed the clicks as a flat line along
the bottom and no columns.
- Reading: a plot group whose value axis isn't the first group's is on the
secondary axis (Series::secondary_axis, now set).
- Model: Chart::series_kind, on_secondary and axis_range (per axis; a combo
stacks only its stacked series).
- Rendering: bar-like series are drawn as bars (clustered or stacked among
themselves), the others as lines/areas over them, each against its own
axis; the secondary axis' labels go on the right. Line series use their
line's colour and width (where PowerPoint keeps them), also in the legend.
Long category labels wrap onto two lines.
Outlines, dashes, arrowheads and ink strokes were drawn under the full
transform, including the mapping of the group's child coordinate space onto its
box. A group whose children use small legacy child coordinates (scale ~1600)
therefore stroked 0.75 pt lines about 1200 pt wide and covered the slide. Inside
a group the outline is now carried through that mapping and stroked under the
slide-level view, so the line width, dash lengths and arrowhead sizes stay in
points, also for groups scaled unevenly.
* ActiveX controls show their pictures
A slide's p:controls are read: each control with a p:pic (the image PowerPoint shows for it,
often a WMF) becomes a picture above the slide's shapes.

* Metafiles draw their text, pattern and hatch brushes
deckcraft-metafile (still kurbo + thiserror only, so it builds for wasm):
- Text: WMF EXTTEXTOUT/TEXTOUT and EMF EXTTEXTOUTW/EXTTEXTOUTA/SMALLTEXTOUT with the
selected font (CREATEFONTINDIRECT, EXTCREATEFONTINDIRECTW: face, signed LOGFONT height,
width, weight, italic, underline, strike-out, escapement, charset), text and background
colour, background mode, TA_* alignment and TA_UPDATECP, the dx array (ETO_PDY pairs too),
ETO_OPAQUE fills and ETO_CLIPPED clips. 8-bit strings decode through their charset
(Windows-1252/1250/1251; symbol fonts keep their codes at U+F000; double-byte sets keep
their advances). The neutral Item::Text carries a text-space-to-picture transform, so the
mapping and escapement are folded in and glyphs are never mirrored.
- Brushes: WMF DIBCREATEPATTERNBRUSH, EMF CREATEDIBPATTERNBRUSHPT and CREATEMONOBRUSH, and
BS_HATCHED, as Item::Pattern tiles in 96-dpi pixels; WMF PATBLT. The XOR / AND-pattern /
XOR see-through shadow of old PowerPoint WMFs draws its pattern in the XOR colour.
- MFCOMMENT escapes with an embedded EMF are ignored: PowerPoint draws the WMF's records.
- Pattern pixels and text count against the byte budget; strings are capped.
deckcraft-render draws text through deckcraft-fonts with the face slide text would use
(document_face), symbol fonts mapped as bullets map them (deckcraft_text::symbol_char, now
public, with Webdings), per-character fallback, the file's advances, GDI cell metrics for
top/bottom alignment, underline/strike-out and synthetic bold/italic. Tiles below 1.5 output
pixels per cell are drawn as their average colour.
On the 24 corpus slides that show a metafile, mean abs diff against PowerPoint goes from
28.31 to 5.06 (with the OLE/ActiveX preview commits).

PowerPoint's Normal view draws shapes, pictures and text that sit partly
or wholly off the slide on the area around it, at full strength, with
their effects, master and layout graphics included; the slide show,
exports and thumbnails clip to the slide. DeckCraft clipped everything to
the slide in the editor too.
- render: `slide_extent`/`layout_extent` estimate how far a slide's
drawing reaches (boxes, outlines, shadow, glow, reflection);
`render_slide_drawn` also reports what a render actually drew (text
spilling out of its box, table rows that grew); `pasteboard_region`
picks the pixels the editor renders: the slide plus what reaches off
it and is in view, rounded to 256 px tiles so scrolling rarely
re-renders. A slide with nothing off it renders exactly as before.
- ui-egui: the canvas texture covers that region (slide and master
views); it re-renders only when the slide, zoom or the region changes,
and a second time only if text drew beyond the estimate.
- Hit testing, selection, marquee and moves already worked in slide
space; tests now cover them off the slide.
