pdf2txt.py HTML output has bad formatting

[f-t-alves]

I've tried out a few of the PDFs found in the samples directory and most had pretty bad formatting. Is this a known limitation or did something go horribly wrong somewhere? For example, trying out samples/font-size-test.pdf with all three layout modes produced overlapping characters, with varying degrees of wonkiness when trying to interactively highlight the text.

To reproduce, run pdf2txt.py -o test.html font-size-test.pdf, then open the HTML in a browser of your choice.
