Negative width for text string

[andrewathalye]

Hello, thank you for writing pdfalto! It’s proven invaluable for making my own DjVu conversion software.

In the attached test file string p1_w47 incorrectly reports a negative width and part of the string should be on the next line, logically speaking.

Excerpt attached:

<String ID="p1_w47" CONTENT="мы̀та́рѧГ" HPOS="297.850" VPOS="287.710" WIDTH="-230.13" HEIGHT="27.7200" STYLEREFS="font4"/>

This test file is a pretty good stress test anyway, with the amount of diacritics it contains. Performance seems to be fine, it’s just the negative width that’s causing a bit of trouble.
