Move Vulkan description from "Graphical Environments" to Mesa
Well, Vulkan is not an alternative of X, nor Wayland.  It's an
alternative of OpenGL.

Change "libvulkan" to "Vulkan-Loader" by the way.  "libvulkan" is a
library, and Vulkan-Loader is the name of the package providing it.  The
URL is also updated because there is no download link at vulkan.org.

<title>Graphical Environments</title>
<para>
This chapter contains instructions to build and configure a graphical
user environment.

<!-- Historical but not very useful now
<para>
<application>Xorg</application>, in addition to clearing up some
licensing issues with <ulink url="http://www.xfree86.org/">XFree86</ulink>,
introduced a completely auto-tooled build for the X Window system. This
means that the packages build and install using the conventional
<command>configure</command>, <command>make</command>, and <command>make
install</command> commands, as opposed to a proprietary build system that
required hand editing of configuration parameters in a C-like syntax.
</para>
<para>
<application>Xorg</application> also brought with it a modular build
system. While this separation into modules resulted in full control of the
features available to the X server on any given installation, it also made
the installation more tedious as it requires installing more than 100
different packages to obtain a functional X Window environment. Most large
commercial distributions have elected to use <application>Xorg</application>
over the <application>XFree86</application> distribution due to both
licensing issues and the increased functionality provided by it over
<application>XFree86</application>. With the modular build system, also came
incremental updates to individual packages. The distribution of
<application>Xorg</application> is given a release number by the developers,
in this case Xorg-&xorg-version;, and is referred to as the "katamari" by
the upstream developers.
</para>
<para>
Additionally, the BLFS book appends a build number
to the end of version string to indicate whether a group of incremental
updates has been applied, while still retaining the versioning scheme of the
upstream developers. For instance, Xorg-&xorg-version;-1 would indicate that
this is the 1st release, and is consistent with the katamari, while
Xorg-&xorg-version;-2 would indicate that individual package updates have
been applied to the katamari.
</para>

<para>
For a long time the only graphical environment usable with GNU/Linux has
been the <emphasis>X Window System</emphasis>. It uses a client/server
model which allows writing applications completely independent of
the graphical hardware. This has the drawback that accessing modern
hardware acceleration is difficult, so another approach named
<emphasis>Wayland</emphasis> is developed.
It is a simpler replacement for X, easier to develop and maintain, using
the OpenGL framework. The main desktop environments GNOME and KDE have
been ported to it.
</para>
<para>
This chapter provides the basic components of the X Window System and
Wayland. For X, the chosen implementation is Xorg, which is a modular
implementation and requires more than 100 packages to be installed. The
distribution of Xorg is given a release number by the developers, in this
case Xorg-&xorg-version;. Individual packages are updated as needed without
changing this number.
