[cairo-announce] [ANNOUNCE] pixman release 0.29.2 now available

A new pixman release 0.29.2 is now available. This is the first
development snapshot leading up to a stable 0.30.0 release.

News in this release:

* Assembly optimizations for the Raspberry Pi and other ARMv6 chips
  [Ben Avison]

* Comprehensive support for high-quality image resampling filters
  [Søren Sandmann]

* Improved precision for matrix arithmetic [Siarhei Siamashka]

Other news include optimizations in the SSE2 backend [Chris Wilson],
in the MIPS DSPr2 backend [Nemanja Lukic], and in the generic C
backend [Siarhei Siamashka], plus a number of bug fixes and
improvements to the test suite.
