Release 2.21.3 (2013-02-20)
==========================A few minor bugfixes, another point release.
* Fix tracking of DRI pixmaps and their backing bo across reparenting. If
we tried to execute a SwapBuffers after a Window was reparented, but
before the DRI client has updated its references, then we would end up
manipulating an exported pixmap without a flush flag set. In the worst
case, this would culminate in a segfault in the driver.
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1127497
* Restore the gen4 workarounds for flickering rendering - a few cases still
remain, as the root cause persists.
https://bugs.freedesktop.org/show_bug.cgi?id=60402
* Double check that the device has KMS enabled before claiming. This allows
X to gracefully fallback to VESA/fbdev rather than bailing out.

* Fix the UXA render programs for projective transforms on Ivybridge.
Complete list of changes since 2.21.2 (not 2.22.2 as I kept typing!)
