Annotations keep the colours they were given (both /AP appearances and the no-/AP Highlight fallback), so a Multiply highlight over a dark background shows the marked-up words in the highlight's colour instead of a flat bar that hides them (#1548). Presets: black on white, white on black, yellow on black, green on black, or a custom #RRGGBB pair; only_black limits the mapping to near-black paints (a 10% luminance threshold — our choice; Acrobat's was not observed). Display only: the document is not changed and print and export are unaffected; print previews and view snapshots render with the document's true colours (a preview matches the uncoloured printout, and a snapshot is an export surface), so reading colours apply to the reading view only. Closes #897 (duplicate #488)."
