+ Subject: cairo snapshot 1.5.14 now available
+
+ A new cairo snapshot 1.5.14 is now available from:
+
+ http://cairographics.org/snapshots/cairo-1.5.14.tar.gz
+
+ which can be verified with:
+
+ http://cairographics.org/snapshots/cairo-1.5.14.tar.gz.sha1
+ af40870b3ec62bbdeaecdf3ea4cce23919fedc42 cairo-1.5.14.tar.gz
+
+ http://cairographics.org/snapshots/cairo-1.5.14.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 1.5.14 tag which points to a commit named:
+ f4d4d7b3d0bd62af6ffd50ba9cd8df0b9a12be71
+
+ which can be verified with:
+ git verify-tag 1.5.14
+
+ and can be checked out with a command such as:
+ git checkout -b build 1.5.14
+
+ This is the seventh snapshot in cairo's unstable 1.5 series. It comes
+ 3 weeks after the 1.5.12 snapshot. This snapshot includes support for
+ arbitrary X server visuals, (including PseudoColor), which was the
+ final remaining cairo-specific item on the cairo 1.6 roadmap. It also
+ includes a huge number of improvements to the cairo-quartz backend. So
+ this is effectively a cairo 1.6 release candidate. We expect very few
+ changes from now until 1.6 and only for specific bug fixes. See below
+ for more about what's new in cairo 1.5.14.
+
+ We do appreciate any testing and feedback you can provide. In
+ particular, if you know of a bug in cairo 1.5.14 that you'd like to
+ see fixed before 1.6.0 and that bug isn't exercised by the cairo test
+ suite, then please make loud noises on the cairo mailing list so that
+ we know about it.
+
+ Have fun with cairo!

+
+ Changes from cairo 1.5.12 to 1.5.14
+ ===================================
+
+ API Change
+ ----------
+ Rename ATSUI font backend to Quartz font backend. This affects the
+ following usage:
+
+ --enable-atsui -> --enable-quartz-font
+ CAIRO_HAS_ATSUI_FONT -> CAIRO_HAS_QUARTZ_FONT
+ CAIRO_FONT_TYPE_ATSUI -> CAIRO_FONT_TYPE_QUARTZ
+
+ cairo_atsui_font_face_create_for_atsu_font_id ->
+ cairo_quartz_font_font_create_for_atsu_font_id
+
+ This API change is justified by the cairo-quartz backend still be
+ marked as "experimental" rather than "supported", (though this is one
+ step toward making the change to "supported" before 1.6). Cairo will
+ still provide ABI compatibility with the old symbol name, however.
+
+ paginated (all of ps, pdf, svg, and win32-printing)
+ ---------------------------------------------------
+ Optimize by not analyzing an image surface for transparency more than
+ once, (previously all images were analyzed twice).
+
+ cairo-ps and cairo-pdf
+ ----------------------
+ Avoiding emitting a matrix into the stroke output when unnecessary,
+ (making output size more efficient).
+
+ Reduce rounding error of path shapes by factoring large scale factors
+ out of the path matrix, (ensuring that a fixed-number of printed
+ digits for path coordinates contains as much information as possible).
+
+ Reduce excess digits for text position coordinates. This makes the
+ output file size much smaller without making the result any less
+ correct.
+
+ cairo-ps
+ --------
+ Eliminate bug causing extraneous text repetition on Linux PostScript
+ output in some cases.
+
+ See: Mozilla Bug 419917 – Printed page contents are reflected
+ inside bordered tables (Linux-only)
+
+ https://bugzilla.mozilla.org/show_bug.cgi?id=419917
+
+ Optimize output when EXTEND_PAD is used.
+
+ cairo-pdf
+ ---------
+ Fix to not use fill-stroke operator with transparent fill, (else PDF
+ output doesn't match the cairo-defined correct result). See:
+
+ https://bugs.launchpad.net/inkscape/+bug/202096
+
+ cairo-svg
+ ---------
+ Fix stroke of path with a non-solid-color source pattern:
+
+ http://bugs.freedesktop.org/show_bug.cgi?id=14556
+
+ cairo-quartz
+ ------------
+ Fix text rendering with gradient or image source pattern.
+
+ Handling antialiasing correctly for cairo_stroke(), cairo_clip(), and
+ cairo_show_text()/cairo_show_glyphs().
+
+ Correctly handle gradients with non-identity transformations:
+
+ Fixes http://bugs.freedesktop.org/show_bug.cgi?id=14248
+
+ Add native implementation of REPEAT and REFLECT extend modes for
+ gradients.
+
+ Fix implementation for the "unbounded" operators, (CAIRO_OPERATOR_OUT,
+ _IN, _DEST_IN, and _DEST_ATOP).
+
+ Correctly handle endiannees in multi-architecture compiles on Mac OS
+ X.
+
+ Avoid behavior which would cause Core Graphics to print warnings to
+ the console in some cases.
+
+ cairo-win32
+ -----------
+ Fix handling of miter limit.
+
+ cairo-win32-printing
+ --------------------
+ Fix to not use a 1bpp temporary surface in some cases while printing,
+ (so grayscale data is preserved rather than just becoming black and
+ white).
+
+ cairo-xlib
+ ----------
+ Add support for rendering to arbitrary TrueColor X server
+ visuals. This fixes at least the following bugs:
+
+ cairo doesn't support 8-bit truecolor visuals
+ https://bugs.freedesktop.org/show_bug.cgi?id=7735
+
+ cairo doesn't support 655 xlib format
+ https://bugs.freedesktop.org/show_bug.cgi?id=9719
+
+ Add support for rendering to 8-bit PseudoColor X server visuals. This
+ fixes the following bug:
+
+ Cairo doesn't support 8-bit pseudocolor visuals
+ https://bugs.freedesktop.org/show_bug.cgi?id=4945
+
+ Unresolved issues (must be fixed before cairo 1.6)
+ --------------------------------------------------
+ XXX: Need to decide if cairo_image_surface_create_for_data should be
+ documented and tested as supporting an image with a negative
+ stride. Also need to decide the correct return value for
+ cairo_format_stride_for_width in case of any error.
