It should be noticed that, in Firefox 4, there are noticeable changes
in font rendering, at least in Windows, due to the introduction of
Direct2D [1] (GPU accelerated widget and font rendering - via
DirectWrite). (Using a beta or a nightly build, one can check/toggle
this feature in "Options" --> "Advanced" --> General --> "Use hardware
acceleration when available", current status can be confirmed by
typing "about:support" in the address bar.) I've seen a couple font
rendering bugs being "solved" by this new approach (for example, bug
543176 [2]), so one should be aware of these changes in the mean time
(and, even afterward, when no hardware support is available/configured
enabled). :-)

On the other hand, I've quickly confirmed that, in *this* particular
case, rendering seems accurate in both versions (3.6.x and a nightly
4.0). ;-)
