MD4C is a push parser without AST so you have to give it
callbacks to generate any koind of intermediate output. You'd
have to make md_parse public in commonmark-d, this is a C-style
My long term goal is indeed super fast conversion of markdown to
PDF, now we have the commonmark parser and the PDF generation, I
just need the time to manage layout. Possibly making a minimal
browser is a better route, dunno.
