+	From: Chris Wilson <chris at chris-wilson.co.uk>
+	To: cairo-announce at cairographics.org
+	Subject: cairo snapshot 1.11.2 now available
+	A new cairo snapshot 1.11.2 is now available from:
+		http://cairographics.org/snapshots/cairo-1.11.2.tar.gz
+	    which can be verified with:
+		http://cairographics.org/snapshots/cairo-1.11.2.tar.gz.sha1
+		40b9e1066fcd33c2aeecd800764b1aa5a0ac7bde  cairo-1.11.2.tar.gz
+		http://cairographics.org/snapshots/cairo-1.11.2.tar.gz.sha1.asc
+		(signed by Chris Wilson)
+	  Additionally, a git clone of the source tree:
+		git clone git://git.cairographics.org/git/cairo
+	    will include a signed 1.11.2 tag which points to a commit named:
+		ac9ee388faf3c8c5df502f6cc7b039f043154954
+	    which can be verified with:
+		git verify-tag 1.11.2

+		git checkout -b build 1.11.2
+	Snapshot 1.11.2 (2011-01-23)
+	===========================
+	In this first snapshot along the way to cairo-1.12.0, we are very excited
+	to announce the introduction of Bezier surface gradients, known as type
+	6/7 gradients in PS/PDF parlance. This is the culmination of much work by
+	the dynamic duo: Adrian Johnson and Andrea Canciani. Thanks guys!
+	Also, I want to warmly welcome Uli Schlachter who recently joined the
+	Cairo community on a mission. That mission is to make cairo-xcb a
+	supported backend for 1.12. And for this snapshot he has made great
+	strides in fixing all the bugs I had left behind. Thanks Uli!
+	And we have also seen a new contributor, Alexandros Frantzis, who has
+	begun bringing up cairo-gl for GLESv2 devices. Thanks Alex!
+	And lastly, I must also thank Adrian and Andrea for the vast numbers of
+	bugs that they have tackled between them, fixing all those little corner
+	cases that lie hidden until too late.
+	-Chris
+	API additions:
+	The ability to construct piece-wise Bezier surface gradients:
+		cairo_pattern_create_mesh
+		constructs a pattern of type CAIRO_PATTERN_TYPE_MESH using
+		cairo_pattern_mesh_begin_patch
+		cairo_pattern_mesh_end_patch
+		cairo_pattern_mesh_curve_to
+		cairo_pattern_mesh_line_to
+		cairo_pattern_mesh_move_to
+		cairo_pattern_mesh_set_control_point
+		cairo_pattern_mesh_set_corner_color_rgb
+		cairo_pattern_mesh_set_corner_color_rgba
+		cairo_pattern_mesh_get_patch_count
+		cairo_pattern_mesh_get_path
+		cairo_pattern_mesh_get_corner_color_rgba
+		cairo_pattern_mesh_get_control_point
+	The introduction of a unique ID accessible via the mime data type:
