However, on Linux the pictures become very ugly. It's very easy to verify, for instance go to google.com, zoom in one level: the letters of the pictures have lots of small "edges". This is documented in the code, in gfx/src/thebes/nsThebesImage.cpp: 599 // See bug 324698. This is a workaround for EXTEND_PAD not being 600 // implemented correctly on linux in the X server. However, since release 1.6, cairo does support CAIRO_EXTEND_PAD correctly: http://www.cairographics.org/news/cairo-1.6.0/ So this workaround for Linux should be removed.
