Animated gifs shrunk without any reason

1. Open url
2. See gif resize, it's  about 550*400, it's resized to favicon size

According to another test this happens if you view the image alone in a tab (icon is created for the tab). After that the image is displayed in icon size if page zoom is exactly 1.0.
It does not happen if it is too large to create an icon.
If you use page zoom on this image weird things happen (make another bug?).

Happened for me after the new cairo landed.

Marco, are you sure about that regression range? I get

Works: 20070801_2338_firefox-3.0a7pre.en-US.win32
Broken: 20070802_0056_firefox-3.0a7pre.en-US.win32

http://bonsai.mozilla.org/cvsquery.cgi?module=PhoenixTinderbox&date=explicit&mindate=1186035660&maxdate=1186041359

Probably due to Cairo 1.5 --> bug 383960

Weird.  I can't reproduce with -chrome foo.gif -width 1000 -height 1000, only with the firefox chrome.  Looking into it...

Attachment: patch for pixman

pixman wasn't correctly resetting the transform if the identity matrix was passed in.
