-From 3f807e104572b38143a1015be57d875088ceaebb Mon Sep 17 00:00:00 2001
-From: Alexander Barton <alex@barton.de>
-Date: Thu, 17 Apr 2014 23:57:38 +0200
-Subject: [PATCH] Test suite: Don't use DNS lookups
-
-Different operating systems do behave quite differently when doing DNS
-lookups, for example "127.0.0.1" sometimes resolves to "localhost" and
-sometimes to "localhost.localdomain" (for example OpenBSD). And other
-systems resolve "localhost" to the real host name (for example Cygwin).
-
-So not using DNS at all makes the test site much more portable.

+across formats is WYSIWYG.  Files are created without the dependence
+on X11 or other external programs.  This device supports alpha
+channel (semi-transparent drawing) and resulting images can contain
+transparent and semi-transparent regions.  It is ideal for use in
+server environments (file output) and as a replacement for other
+devices that don't have Cairo's capabilities such as alpha support or
+anti-aliasing.  Backends are modular such that any subset of backends
+is supported.")
