Andrew Benton 68d013605a Commented out Cairo on the libdrm page,
it seems that libdrm doesn't use Cairo (yet).

<title>Introduction to Cairo</title>
<para>
<application>Cairo</application> is a 2D graphics library with support for
multiple output devices. Currently supported output targets include the
<application>X</application> Window System, win32, image buffers,
PostScript, PDF and SVG. Experimental backends include OpenGL, Quartz and
XCB file output. <application>Cairo</application> is designed to produce
consistent output on all output media while taking advantage of display
hardware acceleration when available (e.g., through the X Render
Extension). The <application>Cairo</application> API provides operations
similar to the drawing operators of PostScript and PDF. Operations in
<application>Cairo</application> include stroking and filling cubic
B&eacute;zier splines, transforming and compositing translucent images,
and antialiased text rendering. All drawing operations can be transformed
by any

There is a reciprocal dependency with the

<application>Poppler</application> packages. As the test suite is
currently unreliable, it is best to simply skip it at this time.

Install <application>Cairo</application> by running the following

make</userinput></screen>
<para>
Note that the tests take a long time to run, many of them fail for unknown
reasons and it has been known to cause a kernel panic. <!-- I suspect that
the panic was due to a bug in the xf86-video-ati driver but I can't be
sure as the system locked up hard. cairo-1.12.0 has exposed bugs in other
parts of Xorg https://bugs.freedesktop.org/show_bug.cgi?id=47266 Andy
