PdfSettings (serde, camelCase) is the Save PDF model: Standard, Compatibility
PDF 1.4-2.0, General (Preserve editing, Thumbnails, Fast web view, View after
saving, Create layers), Compression, Marks and Bleeds, Output, Advanced and
Security. PdfOptions = settings + pages, title and date.
document.exportPdf {path?, preset?, artboard?|artboards?|range?, standard?,
compatibility?, ...sections} -> {path|dataBase64, bytes, warnings} applies the
options over the preset (null keeps the preset's value); PDF/X, passwords,
PDF/A-2b at 2.0 and out-of-range values are refused; options accepted but not
applied yet come back as warnings. document.export {format: pdf} and
document.formats take and list the same options.
The Save PDF dialog (file.export.pdf, ui.savePdfDialog) has Preset,
Standard and Compatibility on top and a section list; it runs the export
before asking for a path, so bad options never open a save dialog.

New Document.page_isolate / page_knockout, set by
transparency.togglePageIsolatedBlending / togglePageKnockoutGroup {value?}
(one undo step each, saved with the document, reported by
transparency.info) and the Transparency panel menu's check items. The page
renders as an isolated group (top-level blend modes no longer blend with
what lies under the page) and/or a knockout group whose elements are the
layers (neutral layers pass their objects through). PDF and SVG wrap the
page content in an isolated group and write page knockout as soft masks.

New Node.knockout_shape (transparency.set / object.setProps knockoutShape,
reported by transparency.info). In a knockout group such an object knocks
out only as much as its opacity and mask let through (a 50% object knocks
out 50%); otherwise its full coverage knocks out. The renderer, PDF and
SVG masks honour it, and the panel's checkbox is now live.

Knockout Group is now Knockout {Neutral, Off, On} (old files' true loads as
On, false as Neutral). In a knockout group each child erases what the
children below it drew where it paints, then adds itself, so it composites
against the group's backdrop; neutral plain groups pass their children
through to the enclosing knockout group. transparency.set / object.setProps
take knockout "on"|"off"|"neutral"|bool; transparency.info reports the
state. PDF and SVG write knockout groups as nested soft masks with the same
look (PDF warns); the Transparency panel has a tri-state checkbox.
