+	Subject: cairo snapshot 1.5.16 now available
+
+	A new cairo snapshot 1.5.16 is now available from:
+
+	        http://cairographics.org/snapshots/cairo-1.5.16.tar.gz
+
+	    which can be verified with:
+
+	        http://cairographics.org/snapshots/cairo-1.5.16.tar.gz.sha1
+	        46e08f540f0abf18dea4b889c82455c556c50f2e  cairo-1.5.16.tar.gz
+
+	        http://cairographics.org/snapshots/cairo-1.5.16.tar.gz.sha1.asc
+	        (signed by Carl Worth)
+
+	  Additionally, a git clone of the source tree:
+
+	        git clone git://git.cairographics.org/git/cairo
+
+	    will include a signed 1.5.16 tag which points to a commit named:
+	        5366c8f483dc7bd40b5d0a184c9b16826007c032
+
+	    which can be verified with:
+	        git verify-tag 1.5.16
+
+	    and can be checked out with a command such as:
+	        git checkout -b build 1.5.16
+
+	This is the eighth snapshot in cairo's unstable 1.5 series. It comes
+	less than two weeks after the 1.5.14 snapshot and it really is a
+	legitimate snapshot, (in spite of sharing this date with that of many
+	bogus announcements). The major change in this snapshot is that the
+	cairo-quartz backend is now officially "supported", including new API
+	to construct a font face from a CGFontRef . Also several bug fixes
+	have been fixed in many backends. See below for details.
+
+	This is definitely a "release candidate" snapshot for cairo 1.6.0. At
+	this point all significant items from the cairo 1.6.0 roadmap are
+	already in this snapshot. See:
+
+		http://cairographics.org/roadmap
+
+	At this point, the only change we are planning to make before cairo
+	1.6 is to change the setting of the infamous buggy_repeat flag,
+	(depending on what we learn from characterizing which X server/driver
+	versions exhibit bugs). We don't anticipate any other changes unless
+	people identify bugs. So please let us know if you find anything. We
+	plan to release cairo 1.6 by the end of this week.
+
+	Have fun with cairo!

+
+	What's new in cairo 1.5.16 compared to cairo 1.5.14
+	===================================================
+	general
+	-------
+	Cairo now depends on pixman 0.10.0 which was recently released. The
+	latest pixman release can always be found alongside cairo releases at:
+
+	   http://cairographics.org/releases
+
+	Increase the precision of color stops for gradients. This fixes a
+	regression in gradient rendering that had been present since the
+	1.5.12 snapshot.
+
+	paginated (all of ps, pdf, svg, and win32-printing)
+	---------------------------------------------------
+	Fix assertion failure when some drawing elements are outside the page
+	boundaries, (this bug was noticed when using Inkscape to print a
+	drawing with landscape orientation to a portrait-oriented piece of
+	paper).
+
+	cairo-ps
+	--------
+	Fix of bug causing incorrect glyph positioning.
+
+	Fix handling of CAIRO_OPERATOR_SOURCE.
+
+	cairo-pdf
+	---------
+	More reduction of unnecessary digits of precision in PDF output.
+
+	Fix handling of CAIRO_OPERATOR_SOURCE.
+
+	cairo-svg
+	---------
+	Fix bug in usage of libpng that was preventing cairo_mask from working
+	with the svg backend.
+
+	Fix transformation of source pattern for cairo_stroke().
+
+	cairo-win32-printing
+	--------------------
+	Fix fallback resolution, (thanks again to inkscape users/developers
+	for helping us find this one).
+
+	cairo-quartz
+	------------
+	Mark the cairo-quartz backend as "supported" rather than
+	"experimental". This means the following:
+
+	    * The backend will now be built by default (if possible).
+
+	    * We are committing that the backend-specific API (as published in
+	      cairo-quartz.h) are stable and will be supported in all future
+	      cairo 1.x releases.
+
+	    * We are committing that the output quality of this backend
+	      compares favorably with other cairo backends, (and that quality
+	      is ensured by good results from the cairo test suite).
+
+	    * We recommend that distributions build and distribute this
+	      backend when possible.
+
+	Note that the cairo_quartz_image API (in cairo-quartz-image.h) is
+	still experimental, will not build by default, (pass
+	--enable-quartz-image to configure to build it), and may see API
+	changes before it is marked as "supported" in a future release.
+
+	Put the CAIRO_FONT_TYPE_ATSUI name back into
+	cairo-deprecated.h. Without this, the cairo 1.5.14 snapshot broke all
+	builds for applications using the C++ cairomm bindings (and perhaps
+	others) which have the CAIRO_FONT_TYPE_ATSUI name in their header
+	files. This breakage happened even for applications not using
+	cairo-quartz at all.
+
+	    Note: Even though the CAIRO_FONT_TYPE_ATSUI name is provided to
+	    avoid this build breakage, we still recommend that bindings and
+	    applications move to the new, and more accurate,
+	    CAIRO_FONT_TYPE_QUARTZ name.
+
+	Replace the implementation of cairo-quartz-font to use CGFont instead
+	of ATSUI. The CGFont API is a better fit than ATSUI, and this new
+	implementation is also more correct than the old one as well.
+
+	This also adds the following new API call:
+
+		cairo_public cairo_font_face_t *
+		cairo_quartz_font_face_create_for_cgfont (CGFontRef font);
+
+	The previous cairo_quartz_font_face_create_for_atsu_font_id function
+	continues to exist and is part of the supported API going
+	forward. (However, the old name of that same function, which was
+	cairo_atsui_font_face_create_for_atsu_font_id is officially
+	deprecated. Any source code using the old name should be updated to
+	use the new name.)
+
+	Fix transformation of source pattern for cairo_stroke().
+
+	cairo-win32
+	-----------
+	Avoid crash in create_similar is cairo_win32_surface_create fails.
