Version 9.0 featuring pdf.js 2.9

Version 9.0 has few new features. Instead, a lot of work went into bugfixes. The most prominent feature is updating from pdf.js 2.7 to pdf.js 2.9. This, in turn, mean better text rendering, improved accessibility support, displaying digital signatures officially (as opposed to the custom hack I offered before), and lots of minor features and bug fixes. pdf.js 2.9 also offers experimental XFA (Acrobat Forms) support, but I doubt you can already access it using ngx-extended-pdf-viewer.

ngx-extended-pdf-viewer itself also contains quite a few bug fixes. Most importantly: I've repaired form support. I've also re-worked the CSS rules. That should make using the library easier.

The only new feature is deals with PDF files you're opening for the second time. Since version 9.0, the original zoom setting is used again. The drawback is that this adds a delay, so you may want to override this commodity feature by setting [zoom] explicitly.
