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.

Applying a gradient swatch records it as the gradient's swatch (the Swatches panel highlights
it and the Gradient panel's swatch menu marks it). A stop given a global or spot swatch (and a
tint) in paint.editGradient / a gradient paint's stops, dropped from the Swatches panel or
picked in the stop popover stays linked: editing the swatch recolours it, in art and in
gradient swatches, deleting it unlinks it. Spot stops separate on their plate, and a gradient
whose stops are all tints of one spot ink (or paper white) exports to PDF as a Separation
shading; gradients mixing models are written in one colour space (the PDF writer requires it;
mixed models used to abort the export).
