Release 2.21.1 (2013-02-10)
===========================
A fix for a potential GPU hang on 945gm (GMA3100) and earlier chipsets,
along with backporting SNA to the packages found in stable distributions
like Debian 6.0 (Squeeze).
* Cleanup compilation warnings from deblint, thanks to Paul Menzel
* Minor build improvements by Damien Lespiau.
* Disable generating span geometry for non-rectilinear spans on gen4
in order to work around and prevent one class of render corruption.
* Prevent cache thrashing and severe performance degradation on LLC
machines for streaming texture updates. However, note the effect was
only observed on just one particular laptop.
* Fix alignment of subsurface proxies for old chipsets.
