- Document properties render as a sidebar with everything pdfium reports:
title, author, subject, keywords, creator, producer, dates, page count,
and file size.
- Rotating pages turns all of them a quarter turn. Rendered bitmaps carry
the rotation, overlay geometry (links, selection, find hits) is mapped
into display space, and hit testing maps clicks back into page space.
- Presentation mode lays out a single fitted page with sidebars, find bar,
and page labels hidden; Escape leaves it.
- Fit to view now also works for PDFs by fitting the current page into the
viewport, which previously only applied to images.
