    news: Add 1.9.8 announcement
    
    I usually get the markdown markup wrong, so I expect this to be no
    exception...

+	To: cairo-announce at cairographics.org
+	Subject: cairo snapshot 1.9.8 now available
+
+	A new cairo snapshot 1.9.8 is now available from:
+
+		http://cairographics.org/snapshots/cairo-1.9.8.tar.gz
+
+	    which can be verified with:
+
+		http://cairographics.org/snapshots/cairo-1.9.8.tar.gz.sha1
+		25f1a445ac0e2b33355ab9bc046b4ee7639554a1  cairo-1.9.8.tar.gz
+
+		http://cairographics.org/snapshots/cairo-1.9.8.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 1.9.8 tag which points to a commit named:
+		3a20b10cd0d94406fbd5fe3bb3d4820a95364537
+
+	    which can be verified with:
+		git verify-tag 1.9.8
+
+	    and can be checked out with a command such as:
+		git checkout -b build 1.9.8
+
+	One major API change since the last snapshot, and a whole slew of bugs
+	fixed and inconsistencies eliminated. Far too many bugs fixed to
+	individually identify. We need to thank Benjamin Otte for his fantastic
+	work on the cairo-gl backend making it faster and more robust, Andrea
+	Canciani for finding so many bugs and developing test cases for them, as
+	well fixing them. And last but not least we must all thank Adrian Johnson for
+	continuing to eliminate bugs and improving the PostScript and PDF backends.
+
+	This snapshot represents almost 4 months of bug fixing, bringing Cairo to
+	a point where we consider it almost ready to be a candidate for release.
+	There are a few known bugs left to be fixed, being tracked in
+	https://bugs.freedesktop.org/show_bug.cgi?id=24384, so please give Cairo a
+	whirl and report any regressions. The plan is to release a new snapshot
+	every other week leading to a 1.10 release with a target date of
+	2010-08-16.

+
+	API additions
+	-------------
+	  CAIRO_FORMAT_RGB16_565
+
+	    16 bit devices still remain popular, and so with great demand,
+	    CAIRO_FORMAT_RGB16_565 has been restored enabling applications to create
+	    and use 16 bit images as sources and render targets.
+
+	  cairo_surface_create_for_rectangle()
+
+	    It is common practice to cut an image up into many smaller pieces and use
+	    each of those as a source - a technique called texture atlasing.
+	    cairo_surface_create_for_rectangle() extends Cairo to directly support use
+	    these subregions of another cairo_surface_t both as a source and as a render
+	    target.
+
+	  cairo_region_create()
+	  cairo_region_create_rectangle()
+	  cairo_region_create_rectangles()
+	  cairo_region_copy()
+	  cairo_region_reference()
+	  cairo_region_destroy()
+	  cairo_region_equal()
+	  cairo_region_status()
+	  cairo_region_get_extents()
+	  cairo_region_num_rectangles()
+	  cairo_region_get_rectangle()
+	  cairo_region_is_empty()
+	  cairo_region_contains_rectangle()
+	  cairo_region_contains_point()
+	  cairo_region_translate()
+	  cairo_region_subtract()
+	  cairo_region_subtract_rectangle()
+	  cairo_region_intersect()
+	  cairo_region_intersect_rectangle()
+	  cairo_region_union()
+	  cairo_region_union_rectangle()
+
+	    The Cairo region API was actually added a couple of snapshots ago, but we
+	    forgot to mention it at the time. A simple API for the handling of
+	    rectangular pixel-aligned regions by Soeren Sandmann.
+	  
+
+	Backend-specific improvements
+	-----------------------------
+	cairo-gl
+
+	  Benjamin Otte made more than 300 commits in which he refactored the cairo-gl
+	  backend, reducing a lot of code duplication and enabled him to begin working
+	  on improving performance by reducing state changes and associated overhead.
+
+	cairo-xlib
+
+	  Access to the underlying connection to the Display is now thread-safe
+	  enabling cairo-xlib to be used in a multi-threaded application without fear
+	  of random corruption. Thanks Benjamin Otte!
+
+	  cairo-xlib will now attempt to use PolyModeImprecise when compositing
+	  trapezoids (i.e. a fill or a stroke operation with a non-trivial path) which
+	  should allow hardware drivers more scope for accelerating the operation at
+	  the cost of potentially incurring minute rendering errors. The mode can be
+	  forced back to PolyModePrecise by setting the antialias parameter to
+	  CAIRO_ANTIALIAS_SUBPIXEL.
+
+	cairo-svg
+
+	  A notable improvement was contributed by Alexander Shulgin to enable SVG to
+	  reference external image through the use an extended MIME data type.
