+ Subject: cairo snapshot 1.5.8 now available
+
+ A new cairo snapshot 1.5.8 is now available from:
+
+ http://cairographics.org/snapshots/cairo-1.5.8.tar.gz
+
+ which can be verified with:
+
+ http://cairographics.org/snapshots/cairo-1.5.8.tar.gz.sha1
+ 8ab70db0eec1db3b730537d9076ddabf7e0ba537 cairo-1.5.8.tar.gz
+
+ http://cairographics.org/snapshots/cairo-1.5.8.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 1.5.8 tag which points to a commit named:
+ 4ccb8cb29546432858e778e1b88cada1327f6f45
+
+ which can be verified with:
+ git verify-tag 1.5.8
+
+ and can be checked out with a command such as:
+ git checkout -b build 1.5.8
+
+ This is the fourth snapshot in cairo's unstable 1.5 series. It comes 2
+ weeks after the 1.5.6 snapshot. It adds a few new API functions. Most
+ notably all callers of cairo_image_surface_create_for_data should now
+ be calling cairo_format_stride_for_width to compute a legal stride
+ value.
+
+ With this snapshot we are getting extrmely close to a final 1.6.0
+ release. We would appreciate as much testing as possible so that we
+ can eliminate bugs before that release rather than after. So give this
+ snapshot a try and let us know how things go for you.
+
+ And have fun with cairo!

+
+ Changes in cairo 1.5.8 since 1.5.6
+ ==================================
+ New API in cairo 1.5.8
+ ----------------------
+ We've added a new function that should be called to compute a legal
+ stride value before allocating data to be used with
+ cairo_image_surface_create_for_data:
+
+ int
+ cairo_format_stride_for_width (cairo_format_t format,
+ int width);
+
+ We've also added a new cairo_path_extents function that can be used to
+ compute a bounding box for geometry such as a single line segment,
+ (contrast with cairo_path_extents and cairo_stroke_extents):
+
+ void
+ cairo_path_extents (cairo_t *cr,
+ double *x1, double *y1,
+ double *x2, double *y2);
+
+ And finally, we've added a function to allow for querying the
+ XRenderPictFormat of a cairo-xlib surface:
+
+ XRenderPictFormat *
+ cairo_xlib_surface_get_xrender_format (cairo_surface_t *surface);
+
+ API changes
+ -----------
+ Fix return types of cairo_surface_show_page and
+ cairo_surface_copy_page. This is an API change to functions that are
+ new in the 1.5 series, so not an API break compared to any stable
+ cairo release, (1.0.x, 1.2.x, 1.4.x).
+
+ Change the return type of cairo_get_current_point() from void to
+ cairo_status_t. This allows the caller to receive a
+ CAIRO_STATUS_NO_CURRENT_POINT value to distinguish the a current point
+ at the origin from no current point existing.
+
+ Performance improvement
+ -----------------------
+ Improve performance of clipping by using an optimized code path
+ internally, (with the ADD operator instead of IN).
+
+ General bug fixes
+ -----------------
+ Fix various cairo_*_extents functions to initialize the return-value
+ variables even in the case of a cairo_t in error.
+
+ Treat NULL as a legitimate value for cairo_font_options_t*. [XXX: On
+ discussion afterwards, we decided against this change so we plan to
+ remove this again before 1.6.0]
+
+ Fix rendering with CAIRO_ANTIALIAS_NONE to be more predictable, (that
+ is, to avoid seams appearing when geometry and imagery share an
+ identical edge). Portions of this fix are in the pixman library and
+ will appear in a future release of that library.
+
+ Avoid triggering an error for a font size of 0.
+
+ Miscellaneous changes
+ ---------------------
+ Require pixman >= 0.9.6.
+
+ There has been a tremendous amount improvement to cairo's
+ documentation. We're delighted that 100% of the public API has at
+ least some documentation in the API reference manual. Many thanks to
+ Behdad Esfahbod and Nis Martensen for leading this effort.
+
+ cairo-pdf and cairo-ps
+ ----------------------
+ Eliminate failure when a Type 1 font is embedded with an explicit
+ glyph 0.
+
+ cairo-pdf
+ ---------
+ Implement a more correct and more efficient approach for patterns with
+ an extend mode of CAIRO_EXTEND_REFLECT.
+
+ cairo-ps
+ --------
+ Fix image masks to properly pack and pad mask bits.
+
+ cairo-quartz
+ ------------
+ Take care to only use DrawTiledImage for integer-aligned images, (and
+ use slower paths to get the correct result in other cases).
+
+ cairo-win32
+ -----------
+ Fix for older versions of mingw.
+
+ Improve the handling of the clipping with the win32 and win32-printing
+ surfaces.
+
+ Fix rendering of non black/white text.
