[ Robert Hooker ]
* New upstream git snapshot up to commit 94118fe2d4b1e5 (LP: #631413)
* New features include ATI HD5xxx series support in r600, and a vastly
  improved glsl compiler.
* Remove pre-generated .pc's, use the ones generated at build time
  instead.
* Remove all references to mesa-utils now that its no longer shipped
  with the mesa source.
* Disable the experimental ARB_fragment_shader option by default on
  i915, it exposes incomplete functionality that breaks KDE compositing
  among other things. It can be enabled via driconf still. (LP: #628930).

[ Christopher James Halse Rogers ]
* debian/patches/04_osmesa_version.diff:
  - Refresh for new upstream
* Bugs fixed in this release:
  - Fixes severe rendering corruption in Unity on radeon (LP: #628727,
    LP: #596292, LP: #599741, LP: #630315, LP: #613694, LP: #599741).
  - Also fixes rendering in gnome-shell (LP: #578619).
  - Flickering in OpenGL apps on radeon (LP: #626943, LP: #610541).
  - Provides preliminary support for new intel chips (LP: #601052).
* debian/rules:
  - Update configure flags to match upstream reshuffling.
  - Explicitly remove gallium DRI drivers that we don't want to ship.
* Update debian/gbp.conf for this Maverick-specific packaging
* libegl1-mesa-dri-x11,kms: There are no longer separate kms or x11 drivers
  for EGL, libegl1-mesa-drivers now contains a single driver that provides
  both backends.
