A pane's ctl read says Collapse and a PDF's PdfFit and PdfTint (`collapsed`, `fit:height tint:full`), and a Dump keeps the PDF's two

Neither showed in the tag or the ctl, and a Restore brought a PDF back
at width fit and the default tint. The ctl read ends with `collapsed`
when it is, and a PDF's `fit:` and `tint:` in the words PdfFit and
PdfTint take; the dump's image record carries pdf_fit and pdf_tint
(empty in older dumps: the defaults).
