libcairo2: Slow tab switching in chromium w/ nvidia

[Przemysław Pawełczyk]

Just a follow-up. According to the comment of Pierre-Loup A. Griffais at

cairo: [nvidia-302] Slow chromium tab switching with cairo-1.12.0
https://bugs.freedesktop.org/49534

the issue should be resolved with the driver 304.30. Copy-pasting
relevant part of debian changelog:

  - Fixed a problem where RENDER Glyphs operations would exhibit severe
    performance issues in certain cases, such as when used with gradients
    by Cairo and Chromium.

It's not yet in unstable, but when it'll get there, I'll try to check
this and confirm. Jindrich Makovicka already confirmed at the
mentioned bugtracker that new driver fixes the problem.

The issue affects a lot of people, thus I think that the best solution
would be the new nvidia driver hitting wheezy before it'll be released
as a stable.

Regards.

P.S. Just in case, I'm CCing: pkg-nvidia-devel
