Bug#557627: iceweasel: Issues with font rendering

[Matteo Riva]

Package: iceweasel
Version: 3.5.5-1
Severity: normal

Iceweasel seems to have some problems with font sizes, as shown in this
screenshot where it's compared to google chrome:

chrome's progression is clearly more linear while iceweasel has some
"spikes": 7pt is much bigger than 6, while being almost equal to 8. Same
thing at 9/10/11 points.

This problem is not limited to 3.5.5 as it happens with iceweasel
3.0.14 as well, all tested on a fresh squeeze install (build of fri nov
20 2009).
