Paste read PDF only from the Windows clipboard and EPS nowhere, so on macOS a copied equation or drawing pasted nothing new (the last thing copied in the app came back). - macOS: the pasteboard's PDF, EPS and SVG are read, ahead of text and bitmaps. - Windows: EPS is read beside PDF. - Everywhere: an .eps file copied in a file manager pastes. - clipboard.importEps loads an EPS into the clipboard as document.open reads one.
