PDF support #145
Description
much discussion has been held over VERT receiving support for the .pdf filetype. nothing has happened so far because of how complicated converting from pdf to another format is.
for example, let's say you have a pdf file, and you need a docx file. as far as i'm aware, pdfs generally don't contain layout information, only raw positions for various elements, which doesn't work for a docx which does use a proper layout engine to position elements on the screen. how would this be handled?
also consider scanned pdfs, which are essentially just jpeg slideshows with technically no textual content. people wouldn't want their outputted document to be a bunch of images!
the file format itself is also fairly complex, being notoriously hard to parse and get information out of.
