cairo release 1.16.0 now available

After four years of development since 1.14.0, version 1.16.0 of the cairo 2D graphics library has been released. 'Of particular note is a wealth of work by Adrian Johnson to enhance PDF
functionality, including restoring support for MacOSX 10.4, metadata,
hyperlinks, and more.

Much attention also went into fonts, including new colored emoji glyph
support, variable fonts, and fixes for various font idiosyncrasies.

Other noteworthy changes include GLESv3 support for the cairo_gl
backend, tracking of SVG units in generated SVG documents, and cleanups
for numerous test failures and related issues in the PDF and Postscript
backends.' More information can be found in the change log.
