The cairo team is very pleased to announce cairo 1.0 released. So what is it? Cairo is a 2D graphics library with support for multiple output devices. Currently supported output targets include the X Window System, win32, and image buffers. Experimental backends include OpenGL (through glitz), Quartz, XCB, PostScript and PDF file output.
I had a little to do with some fixes for it and have been packaging it for Debian since 2003 (debs). It's nice to see it get out there as it's the smarts behind things in the latest GTK+ 2.8 and other projects such as SVG support in Mozilla (possibly) and 2D drawing graphics for GNU classpath and Mono.
