Can't Zoom Out of Some PDFs

[TechD123]

Since I started using the app with version 3.19, some PDFs are displayed with a zoom factor above 100% when opening them, meaning the entire page can't be seen. It's impossible to make the entire page fit, even though the document appears to be A4 sized. In my experience, this has affected 1/10 PDFs.

The problem is still present in 3.26.

Here's a link to a PDF for which this is the case.

@TomTasche @ViliusSutkus89 I suppose this is something that changed with the pdf2htmlEX update?

[ViliusSutkus89]

3.19 was built against pdf2htmlEX-Android 0.18.16, which was built against pdf2htmlEX-v0.18.7-poppler-0.81.0
3.24 is built against pdf2htmlEX-Android 0.18.23, which is built against pdf2htmlEX-0.18.8.rc1 + rc2 patches

So yes, there were a lot of changes both in our packaging and in the upstream pdf2htmlEX.

I got some luck getting the document to fit properly by using setFitWidth, which calls fit-width, but I'm not entirely sure what's the proper default value for it

We could add a settings menu to expose those options as configurables

Reproducible with 3.32-pro

Could you use the screen width? Maybe with a static offset of 50 pixel or so, to make sure we don't overlap with scrollbar, etc.
