--- Comment #3 from Miklos Vajna <vmiklos at collabora.co.uk> ---
I'm not sure right now. In case the "sharpness" is because we render the PDF
into a bitmap with pdfium, and the size of the bitmap is too small (because the
PDF reports a small logic size), then this is not a bug in pdfium itself, but
in our integration.

However, rendering via pdfium is a new feature, so I think this is rather an
implementation error to fix, than an easy regression to address.

One way to address this could be to not render the pdf immediately on import,
rather only when it gets displayed, and then we can work with the user-defined
size of the picture, not the in-PDF logic size. But that would probably slow
down scrolling, so it'll also need a cache -- so needs some thinking first.
