// repeats the PDF layout with the structure of pages.
// The markup of such documents is very complex and have a lot of tags styled by (x,y) coords.
// HTML-Flowing is better for further processing by a human: editing and combining.
// The markup of such documents is much simple inside and has the flowing structure.
// It's very simple for understanding by a human.
// But the resulting HTML document doesn't look exactly the same as input PDF pixel by pixel.
