  1. Multi-step flattening to massively improve the quality of the generat… 

    …ed PDF's.

PDF viewing software such as preview and acrobat reader auto positions the unflattened form fields when the user views the PDF file in it. But the `pdftk` library doesn't auto position fields before flattening. The `pdftk` does support the ability to create better-positioned fields without flattening using its `need_appearances` option.
ref. https://www.pdflabs.com/docs/pdftk-man-page/#dest-output-need-appearances

So, we are using a multi-step approach to get the same quality from the `pdftk`, which does the following:
1. fill-up the form with the `need_appearances` flag and without the `flatten` flag
2. regenerating the flattened file out of the non-flattened PDF file, which has better positioning.

Empirical results have shown massive improvements in the quality of the generated PDF's: https://ibb.co/KLqtYJC
