[ANNOUNCE] xf86-video-intel 2.21.11

Release 2.21.11 (2013-06-30)
============================
An eventful week. What started with a regression with some builds of
firefox on some machines lead ultimately to the discovery of an older
kernel bug. Aside from the work to fix the image bug and a few other
older bugs that were reported and resolved this week, there is also a
(hopefully) subtle change to the initial configuration of displays. In
the absence of user overrides in xorg.conf, the DDX will try to preserve
the same display configuration as used by the kernel, which hopefully
will be the same configuration as setup by the BIOS. The result should
be a boot sequence that does not resize at all (aka fastboot) - until
the display manager takes over and loads a completely different
configuration!

 * Fix occasional missing images for inplace uploads
   [regression from 2.21.10]
   https://bugs.freedesktop.org/show_bug.cgi?id=66059

 * Add missing utility files to the tarball and remove a few unused ones

 * Initialise PolyPoint operand state before calling miWideDash
   https://bugs.freedesktop.org/show_bug.cgi?id=66104

 * Fix redirection handling for rendering into large surfaces
   https://bugs.freedesktop.org/show_bug.cgi?id=66168
   https://bugs.freedesktop.org/show_bug.cgi?id=66249

 * Fix compilation of UXA with xorg-xserver < 1.10
   [regression from 2.20.0]

 * Fix consideration of gradients for deciding when to migrate render
   operations
   [performance regression from 2.21.10, the bug itself is older]

    drm/i915: Only clear write-domains after a successful wait-seqno

which affects kernels 3.7 - 3.10, coming to a stable kernel near you soon.
