The reader stored a series-level `c:dLbls/c:showVal` in
`Series.data_labels`, but every drawing path tested only the chart-wide
`Chart.data_labels`: a series that asked for labels got none, and a
series that asked for none got them. The series' own setting now wins,
and a bare `<c:showVal/>` (no `val` attribute) means true, as the
schema's default.
The plot group's own setting is respected too: a group that asks for no
labels keeps them off, even when another group of a combo chart asks for
them. Before, any group that asked turned the chart-wide setting on, and
the group that said no inherited it.
Tests: `crates/pptx/tests/chart_data_labels.rs` - a bare series
`showVal` shows that series' labels while its siblings stay quiet; an
explicit `val="0"` on the first series keeps it quiet under a chart-wide
on; a combo chart keeps each group's own setting; all three settings
round-trip. Red-proof: with the series-level setting ignored, the first
two fail; with the group's setting ignored, the combo chart's bar group
shows labels it asked to keep quiet.
The model gains `Chart::series_data_labels`, the one place that decides
whether a series' labels show; the render paths (bar, column, line,
area, pie, doughnut, radar, scatter) call it.
The fix changed the empty-placeholder fill gate, but nothing locked the
behaviour in: a quick style's fill has to appear on an empty placeholder,
and a placeholder with no style at all still has to stay empty.
The new render test draws an empty body placeholder in the editor with a
quick style and checks that the accent fill is painted - every channel of
it - and that the same placeholder without a style stays white. With the
gate reverted to `s.fill.is_none()` alone the first assertion fails - the
placeholder stays white - so the test is red on the unfixed code.
The render gate for an empty placeholder's fill checked only
s.fill.is_none(). A quick style that sets a style reference without
an explicit fill left s.fill as None, so the gate skipped the fill
even though the shape had been formatted — the style only appeared
after text was added.
The gate now also checks s.line and s.style: if any of the three has
a local override, the placeholder is considered formatted and the
fill is drawn. A truly unformatted empty placeholder still shows the
dashed outline and prompt.
The renderer lays every slide background over white (as PowerPoint does),
so a PNG export was always opaque. A new transparentBackground option leaves
the slide background out (both the white underlay and the background fill),
so only what is on the slide is drawn over transparency. Shapes filled with
the background (useBgFill) still show it.
- render: RenderOpts::transparent_background
- engine: file.export {transparentBackground} (PNG only; other formats
refuse it and write nothing), file.render {transparentBackground}
- UI: Transparent background checkbox in the Export dialog (PNG) and in
File > Export > Change File Type > PNG; the web download honours it
- CLI: render --transparent
A picture was decoded at the size of its box on screen. A cropped picture
shows only part of the image, magnified, so it was decoded at a fraction of
the resolution it needs and stretched back up: Merge Shapes > Intersect,
which crops the picture to the new smaller box, left it visibly blurred.
Size the decode from the rectangle the whole image occupies instead.
Conflicts resolved onto main's newer shape, and the PR's policy applied to
every alloc_id/add_media/new_slide call site main has grown since: commands
answer bad(cmd, NO_ID_SPACE) (slide.reuse, insert.zoom, SmartArt, photo
album, review.accept, handout/notes masters, master placeholders,
background/artistic/compress pictures, transition sound, ink to shape,
paste special, file.new templates); reid/bring_media/renumber/regenerate
and compare::adopt/accept are fallible; outline import keeps what fit.
Tests use expect() on the now-Option results.

Fix-ups in the merge (review): zoom targets, sections and titles are looked up with get()
instead of indexing; Hyperlink literals carry both main's sound fields and zoom_return;
duplicated test statements left by the test-file union are removed.

Fix-ups in the merge (review): uniform-width and highlighter strokes are drawn as one path (on
the slide and in the live preview) so see-through ink doesn't darken where segments overlap;
segment pairs are destructured instead of indexed; tests that build pointer events set the new
pressure field.

Fix-ups in the merge: error-bar statistics are computed once per series (was once per point,
quadratic on long series); reading custom amounts uses the chart-wide point budget (#480).

#666's minor gridlines stepped in value units, but #669 scales a log axis in
exponents of its base; map each minor step back through the base.

#662 gives scatter and bubble charts one x scale over every series; #603's
trendlines still mapped x over each series' own extent, so a fit drifted off
its points. Use the chart's x scale where there is one.

#640 orders category slots bottom-to-top on horizontal bars (or reversed via
c:orientation) while #603 pads the axis for trendline forecasts. Slots now
include the forecast padding on the right side, and trendlines map their
category positions through the same slot order as the bars.

f64::clamp panics when the plot is narrower than the caption's minimum width;
use main's clamp_soft, as the rest of the chart code now does.
