flattener.preview {highlight, overprints?, preset?|options?, ids?} reports, without changing the
document, the transparent and affected objects, patterns, outlined strokes and type, rasterized
complex regions, all rasterized areas and flat-colour regions (FlattenReport, worked out by the
flattener's own plan without rendering images). The panel previews a snapshot taken on Refresh,
greyed with the chosen highlight in red, zoomable (click, Alt-click, drag, double-click); its
Overprints, preset and options (Show Options) set how it flattens, and its menu saves them as a
preset. ui.flattenerPreview drives it; the settings persist with the UI state.
