* M6: a pasted image the clipboard doesn't carry shows as missing and is named (#1646) The placeholder an import stores for an image it lacks is now striped, not flat grey; the fill keeps the image's name; .fig and paste give a fixed, translated note per image; edit.pasteDesignLayers returns missingImages, the paste's message names those layers, and a paste with notes opens the import report. * M6: the missing-image placeholder's stripes stay clean when scaled, and a .fig gives one note (#1646)

//! Layers pasted from another design app whose image the clipboard doesn't carry (#1646): the
|

//! paste names them (`missingImages`), and they keep their image's name. Design data made by our

//! own `.fig` export: its canvas alone, as a clipboard carries it, and the whole file with images.
