- DisplayInfo kinds 0/1 (selected / masked areas) now import as alpha channels instead of black
spot inks; a Multichannel composite still prints them as black ink, so the look is unchanged.
- Saving a Multichannel PSD writes global light, grid and guides, saved / work / clipping paths,
EXIF and every other imported resource (print settings, IPTC, layer-id seed, alpha ids while
they match the channels), except the ones that only describe layers, plus the document-level
tagged blocks (4-byte padded). Path writing and global-block padding are shared with the
layered writer.
