Allow Scaling all pages to fit viewer width

[drexhacker]

@espresso3389 Thanks for this amazing package that has really simplified my work as I just shifted from using printing package which is also based on pdfium . I landed on this package and it works very well and actually performs way better than the previous one I was using. But there is just one thing I liked about the previous one and I haven't been to archive the same with this package and it is that in the previous all my pages are rendered in the same size for instance A4 despite the difference in page sizes and for this one I have so far failed to archive the same. Here is an image of how my pages are being rendered with this Package; As seen above I would like the pages to scale to fit atleast to viewer width.

So far I have tried rendering with horizontal scroll and it is more readable but still this is not my intended scrolling axis.

Any help is appreciated Thank You!
