[ANNOUNCE] xf86-video-intel 2.20.8

[Chris Wilson]

Another new small feature, another new release. And a few more bugs
fixed as well! But what is this new feature, do I hear you ask? Why, it
is nothing less than enabling the ValleyView SDV! The lucky person to
have their hands on one will now be able to enjoy X in full TechniColor.

For the rest of us, a few more bugs were fixed with interesting
combinations of software and rendering patterns.

 * Add an extra layer of defence against trying to use a non-GEM device
   with UXA. This should already be taken care of with the new probe,
   but the extra sanity check already existed in the code but was doing
   nothing.
   https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/962892

 * Fix computation of valid CRTCs bitmask for ZaphodHead
   Some systems can only handle certain outputs on certain pipes
   (Screens), and this information was not being propagated through to X
   and randr correctly, breaking valid configurations and not detecting
   invalid configurations correctly.

 * Disable global glyph caching with ZaphodHeads.
   The glyph privates need to be Screen private, but at the moment are
   global leading to conflicts and invalid rendering with multiple heads.
   https://bugs.freedesktop.org/show_bug.cgi?id=54707

 * Prevent direct read back of unmappable buffers
   https://bugs.freedesktop.org/show_bug.cgi?id=54808

 * Tile large uploads whilst replacing the alpha channel
   https://bugs.freedesktop.org/show_bug.cgi?id=54808

 * Correct the source offset when converting a RENDER composite
   operation into a BLT composite operation.
   https://bugs.freedesktop.org/show_bug.cgi?id=54868

 * Correct a minor typo in flattening alphamaps which caused the
   replacement pixmap to often end up with a height of zero.
   https://bugs.gentoo.org/show_bug.cgi?id=434860

 * Don't discard the CPU damage if only part is being replaced.
   This is most evident when combining software renders like Opera with
   accelerated rendering.
