[ANNOUNCE] xf86-video-intel 2.18.0

Time passes, a few more bugs have crept out of the woodwork that are a
compelling reason to update.

Bugs fixed in this release (compared to 2.17.0)

* Limit maximum object size so that all of the source, mask and
  destination can be mapped into the aperture simultaneously by basing the
  limit on the mappable aperture size rather than the size of the total

* Incorrect clipping of polygons
  Regression from 2.15.901

* Limit number of VMA cached to avoid hitting the per-process VMA limit
  There still is a residual bug in that we seem to have so many objects
  floating around in the first place and that still leads to exhaustion
  of system limits.

* Latency in processing user-input during continuous rendering

Other News

As you may have noticed, we now have two additional experimental
acceleration backends, SNA and Glamor. SNA is a continuation of the
traditional DDX model and has a specialised renderer to try and exploit
the full limits of the available hardware. Glamor is an alternate that
hands over all the rendering to a new library that tries to leverage
OpenGL to accelerate the drawing operations. Both require you to have an
uptodate graphics stack (with additional restrictions on how you have
compiled mesa and the xserver for glamor) and to opt in by either
compiling with --enable-sna or with --enable-glamor.

Have fun,
