A terminal's petscii:on survives Dump and Restore: the dump says it, and the restored terminal draws its graphics as glyph art again

An image pane's Petscii choice was dumped; a terminal's was not, so a
Restore brought it back drawing pixels. dump.Terminal carries petscii,
and a restored terminal is turned to glyph art when it was.
