========================================================================

+This new stable release incorporates a number of improvements made in

-For a complete log of changes since 1.14.10, please see:

+Much attention also went into fonts, including new colored emoji glyph

+backends.
-Features
---------
+For a complete log of changes, please see
+
+ https://cairographics.org/releases/ChangeLog.1.16.0
+
+
+Features and Enhancements
+-------------------------
+* Add support for OpenGL ES 3.0 to the gl backend.
+* The PDF backend has gained support for a range of widely used
+ features, including thumbnails, page labels, metadata, document
+ outlines, structured text, hyperlinks, and tags. Tags permit adding
+ logical info such as headings, tables, figures, etc. that facilitates
+ indexing, accessibility, text reflow, searching, and extraction of the
+ tagged items to other software. For details on this new PDF
+ functionality, see:
+ https://lists.cairographics.org/archives/cairo/2016-June/027427.html
+* Variable font support. Variable fonts are single font files with
+ various typography characteristics, such as weight or slant, that users
+ of the font can adjust between two points. Effectively this enables a
+ single font to behave as multiple fonts.
+* Restore MacOSX 10.4 support. Cairo had dropped 10.4 support when
+ moving to the CoreText API. Now we automatically detect which API to
+ use via dynamic linking, so can resume supporting this older version
+ of MacOSX.
+* Support colored emoji glyphs, stored as PNG images in OpenType fonts.
+* Skia backend is removed
+* Use Reusable streams for forms in Level 3 Postscript.
+* Add CAIRO_MIME_TYPE_EPS mime type for embedding EPS files.
+* Add CCITT_FAX mime type for PDF and PS surfaces
+* svg: add a new function to specify the SVG document unit
+ (Bug #90166)
+* Use UTF-8 filenames on Windows
+
+
+API Changes
+-----------
+Several new APIs were added. No existing APIs were altered.
+
+New PDF functionality:
+
+ * cairo_pdf_surface_add_outline
+ * cairo_pdf_surface_set_metadata
+ * cairo_pdf_surface_set_page_label
+ * cairo_pdf_surface_set_thumbnail_size
+ * cairo_tag_begin
+ * cairo_tag_end
+ * CAIRO_STATUS_TAG_ERROR
+
+New error status items for problems relating to PDF tagging:
+
+ * CAIRO_STATUS_WIN32_GDI_ERROR
+ * CAIRO_STATUS_FREETYPE_ERROR
+ * CAIRO_STATUS_PNG_ERROR
+
+ New error status items for handling of GDI, libfreetype, and libpng
+ errors, respectively.
+
+
+Setting up Win32 surfaces for HDC with alpha channels:
+
+ * cairo_win32_surface_create_with_format
+
+ New API for added PDF functionality (see above), and new error
+ status item for problems relating to PDF tagging.
+
+Variable fonts:
+
+ * cairo_font_options_get_variations
+ * cairo_font_options_set_variations
+
+Tracking units in SVG documents:
+
+ * cairo_svg_surface_set_document_unit
+ * cairo_svg_surface_get_document_unit
+
+
+
+Dependency Changes
+------------------
+None
+
+
+Performance Optimizations
+-------------------------
+None
+
+
+Notable Bug Fixes
+-----------------
+* Fix thin lines that don't show up when printing in Inkscape due to
+ overly aggressive culling.
+ (Bug #77298)
+* Fix playback of recording surfaces into PDF surfaces, where objects
+ with negative coordinates were not getting drawn. To address this,
+ the coordinate systems for PDF and PS have been changed to match
+ cairo's coordinate system. This allows recording surfaces to be
+ emitted in cairo coordinates, and results in the same origin being
+ used for all operations when using the recording surface XObject.
+ Test cases for PDF and PS have also been updated accordingly.
+ (Bug #89232)
+* Fix "invalidfont" error on some printers when printing PDFs with
+ embedded fonts that have glyphs (such as spaces) with
+ num_contours == 0. (Bug #79897)
+* Fix missing glyphs such as thin dashes, which get scaled to 0 in
+ userspace and thus have their drawing operations culled. (Bug #94615)
+* Fix other oddities caused by variously idiosyncratic fonts.
+* Fix a data race in freed_pool discovered by Firefox's cairo usage.
+ The patch adads atomic int load and store functions, with relaxed
+ memory ordering. (Bug #90318)
+* Handle SOURCE and CLEAR operators when painting color glyphs.
+ (Bug #102661)
+* Fix falling back to system font with PDFs using certain embedded
+ fonts, due to truncated font names.
+ (Bug #103249)
+* Prevent curved strokes in small ctms from being culled from vector
+ surfaces
+ (Bug #103071)
+* Fix assertion hit with PDFs using Type 4 fonts rendered with user
+ fonts, due to error when destroying glyph page.
+ (Bug #103335)
+* Prevent invalid ptr access for > 4GB images.
+ (Bug #98165)
+* pdf: Fix internal links pointing to other pages, by pre-calculating
+ page heights so that link positions can be calculated more accurately.
+* Fix error reporting in the xcb backend if fallback fails. Instead of
+ returning NULL when the X11 server can't do some operation, return a
+ surface in an error state.
+* Clarify documentation regarding device scale inheritance and the units
+ used in cairo_surface_create_similar_image.
+ (Bug #99094)
+* Call XSync in the xlib backend before setting the error handler to
+ ignore errors for certain requests, to make sure all pending errors
+ are handled first.
+* Fix regression with text containing space character on Win32.
+ (Bug: https://gitlab.freedesktop.org/cairo/cairo/issues/339)

+individual 1.15.x releases.

+Release 1.15.14 (2018-09-19 Bryce Harrington <bryce@bryceharrington.org>)
+============================================================================
+We're nearly ready to finalize the 1.16.0 release, so this snapshot
+can be considered a beta for 1.16.
+
+The most notable change this release is a performance optimization for
+windows, discussed below. Other than that, much of the development
+focus was on final polish and stability as we prepare for 1.16.
+
+Some attention went into getting the testsuite passing at least for the
+image backend. The Cairo testsuite depends on external software like
+Pixman, and changes in the rendering behavior of these dependencies
+change test behavior, leading to false positives.
+
+Results from the Coverity static testing tool were also reviewed. Most
+of the issues flagged were false positives, but there were several
+legitimate problems found and fixed.
+
+For a complete log of changes, please see
+
+ https://cairographics.org/releases/ChangeLog.1.15.12
+
+Features and Enhancements
+-------------------------
+* Add more FreeeType font color conversions to support COLR/CPAL
+* Update test reference images against current pixman
+
+API Changes
+-----------
+None
+
+Dependency Changes
+------------------
None
+Performance Optimizations
+-------------------------
+Vasily Galkin introduced a Win32 performance optimization for
+CAIRO_OPERATOR_SOURCE when copying data from a backbuffer to an argb32
+surface corresponding to a Win32 DC. With this, argb32 drawing should
+perform as fast as typical dibsection-buffered GDI drawing. See the
+Cairo mailing list for April 2018 for data and discussion of the
+performance improvements.
+
+
+Bug Fixes
+---------
+* Fix crash when rendering Microsoft's Segoe UI Emoji Regular font.
+* Fix build breakage with glesv3 enabled due to non-existant glesv3.pc.
+* Fix memory leaks found by Coverity
+* Fix incorrect null ptr handling found by Coverity
+* Fix test compilation when font-config is disabled
+* Use _cairo_malloc instead of malloc (Bug #101547) (CVE-2017-9814)
+* Fix assertion failure in the freetype backend (Bug #105746)
+
+
+Release 1.15.12 (2018-04-04 Bryce Harrington <bryce@osg.samsung.com>)
+========================================================================
+The main focus for this release is the addition of Variable Font
+support. Variable fonts are single font files with various typography
+characteristics, such as weight or slant, that users of the font can
+adjust between two points. Effectively this enables a single font to
+behave as multiple fonts.
+
+The Skia backend is disabled in this release, due to severe bitrot, and
+will be removed in future releases. Contact the cairo team if you have
+a need of this backend.
+
+For a complete log of changes, please see
+
+ https://cairographics.org/releases/ChangeLog.1.15.12
+
+Features and Enhancements
+-------------------------
+* Variable font support
+* Skia backend is disabled
+
API Changes
-----------
+* cairo_font_options_get_variations() and
+ cairo_font_options_set_variations() are added.
+
+Dependency Changes
+------------------
+None
+
+Performance Optimizations
+-------------------------
None
+Bug Fixes
+---------
+* Fix errors in csi-trace --help and --version options

+
+* Fix playback of recording surfaces into PDF surfaces, where objects
+ with negative coordinates were not getting drawn. To address this,
+ the coordinate systems for PDF and PS have been changed to match
+ cairo's coordinate system. This allows recording surfaces to be

+/**
+ * SECTION:cairo-tag
+ * @Title: Tags and Links
+ * @Short_Description: Hyperlinks and document structure
+ * @See_Also: #cairo_pdf_surface_t
+ *
+ * The tag functions provide the ability to specify hyperlinks and
+ * document logical structure on supported backends. The following tags are supported:
+ * * [Link][link] - Create a hyperlink
+ * * [Destinations][dest] - Create a hyperlink destination
+ * * [Document Structure Tags][doc-struct] - Create PDF Document Structure
+ *
+ * # Link Tags # {#link}
+ * A hyperlink is specified by enclosing the hyperlink text with the %CAIRO_TAG_LINK tag.
+ *
+ * For example:
+ * <informalexample><programlisting>
+ * cairo_tag_begin (cr, CAIRO_TAG_LINK, "uri='https://cairographics.org'");
+ * cairo_move_to (cr, 50, 50);
+ * cairo_show_text (cr, "This is a link to the cairo website.");
+ * cairo_tag_end (cr, CAIRO_TAG_LINK);
+ * </programlisting></informalexample>
+ *
+ * The PDF backend uses one or more rectangles to define the clickable
+ * area of the link. By default cairo will use the extents of the
+ * drawing operations enclosed by the begin/end link tags to define the
+ * clickable area. In some cases, such as a link split across two
+ * lines, the default rectangle is undesirable.
+ *
+ * @rect: [optional] The "rect" attribute allows the application to
+ * specify one or more rectangles that form the clickable region. The
+ * value of this attribute is an array of floats. Each rectangle is
+ * specified by four elements in the array: x, y, width, height. The
+ * array size must be a multiple of four.
+ *
+ * An example of creating a link with user specified clickable region:
+ * <informalexample><programlisting>
+ * cairo_font_extents_t font_extents;
+ * cairo_text_extents_t text1_extents;
+ * cairo_text_extents_t text2_extents;
+ * char attribs[100];
+ * const char *text1 = "This link is split";
+ * const char *text2 = "across two lines";
+ *
+ * cairo_font_extents (cr, &font_extents);
+ * cairo_move_to (cr, 450, 50);
+ * cairo_text_extents (cr, text1, &text1_extents);
+ * cairo_move_to (cr, 50, 70);
+ * cairo_text_extents (cr, text2, &text2_extents);
+ * sprintf (attribs,
+ * "rect=[%f %f %f %f %f %f %f %f] uri='https://cairographics.org'",
+ * text1_extents.x_bearing,
+ * text1_extents.y_bearing,
+ * text1_extents.width,
+ * text1_extents.height,
+ * text2_extents.x_bearing,
+ * text2_extents.y_bearing,
+ * text2_extents.width,
+ * text2_extents.height);
+ *
+ * cairo_tag_begin (cr, CAIRO_TAG_LINK, attribs);
+ * cairo_show_text (cr, "This is a link to the cairo website");
+ * cairo_move_to (cr, 450, 50);
+ * cairo_show_text (cr, text1);
+ * cairo_move_to (cr, 50, 70);
+ * cairo_show_text (cr, text2);
+ * cairo_tag_end (cr, CAIRO_TAG_LINK);
+ * </programlisting></informalexample>
+ *
+ * There are three types of links. Each type has its own attributes as detailed below.
+ * * [Internal Links][internal-link] - A link to a location in the same document
+ * * [URI Links][uri-link] - A link to a Uniform resource identifier
+ * * [File Links][file-link] - A link to a location in another document
+ *
+ * ## Internal Links ## {#internal-link}
+ * An internal link is a link to a location in the same document. The destination
+ * is specified with either:
+ *
+ * @dest: a UTF-8 string specifying the destination in the PDF file to link
+ * to. Destinations are created with the %CAIRO_TAG_DEST tag.
+ *
+ * or the two attributes:
+ *
+ * @page: An integer specifying the page number in the PDF file to link to.
+ *
+ * @pos: [optional] An array of two floats specifying the x,y position
+ * on the page.
+ *
+ * An example of the link attributes to link to a page and x,y position:
+ * <programlisting>
+ * "page=3 pos=[3.1 6.2]"
+ * </programlisting>
+ *
+ * ## URI Links ## {#uri-link}
+ * A URI link is a link to a Uniform Resource Identifier ([RFC 2396](http://tools.ietf.org/html/rfc2396)).
+ *
+ * A URI is specified with the following attribute:
+ *
+ * @uri: An ASCII string specifying the URI.
+ *
+ * An example of the link attributes to the cairo website:
+ * <programlisting>
+ * "uri='https://cairographics.org'"
+ * </programlisting>
+ *
+ * ## File Links ## {#file-link}
+ * A file link is a link a location in another PDF file.
+ *
+ * The file attribute (required) specifies the name of the PDF file:
+ *
+ * @file: File name of PDF file to link to.
+ *
+ * The position is specified by either:
+ *
+ * @dest: a UTF-8 string specifying the named destination in the PDF file.
+ *
+ * or
+ *
+ * @page: An integer specifying the page number in the PDF file.
+ *
+ * @pos: [optional] An array of two floats specifying the x,y
+ * position on the page. Position coordinates in external files are in PDF
+ * coordinates (0,0 at bottom left).
+ *
+ * An example of the link attributes to PDF file:
+ * <programlisting>
+ * "file='document.pdf' page=16 pos=[25 40]"
+ * </programlisting>
+ *
+ * # Destination Tags # {#dest}
+ *
+ * A destination is specified by enclosing the destination drawing
+ * operations with the %CAIRO_TAG_DEST tag.
+ *
+ * @name: [required] A UTF-8 string specifying the name of this destination.
+ *
+ * @x: [optional] A float specifying the x coordinate of destination
+ * position on this page. If not specified the default
+ * x coordinate is the left side of the extents of the
+ * operations enclosed by the %CAIRO_TAG_DEST begin/end tags. If
+ * no operations are enclosed, the x coordidate is 0.
+ *
+ * @y: [optional] A float specifying the y coordinate of destination
+ * position on this page. If not specified the default
+ * y coordinate is the top of the extents of the
+ * operations enclosed by the %CAIRO_TAG_DEST begin/end tags. If
+ * no operations are enclosed, the y coordidate is 0.
+ *
+ * @internal: A boolean that if true, the destination name may be
+ * omitted from PDF where possible. In this case, links
+ * refer directly to the page and position instead of via
+ * the named destination table. Note that if this
+ * destination is referenced by another PDF (see [File Links][file-link]),
+ * this attribute must be false. Default is false.
+ *
+ * <informalexample><programlisting>
+ * /&ast; Create a hyperlink &ast;/
+ * cairo_tag_begin (cr, CAIRO_TAG_LINK, "dest='mydest' internal");
+ * cairo_move_to (cr, 50, 50);
+ * cairo_show_text (cr, "This is a hyperlink.");
+ * cairo_tag_end (cr, CAIRO_TAG_LINK);
+ *
+ * /&ast; Create a destination &ast;/
+ * cairo_tag_begin (cr, CAIRO_TAG_DEST, "name='mydest'");
+ * cairo_move_to (cr, 50, 250);
+ * cairo_show_text (cr, "This paragraph is the destination of the above link.");
+ * cairo_tag_end (cr, CAIRO_TAG_DEST);
+ * </programlisting></informalexample>
+ *
+ * # Document Structure (PDF) # {#doc-struct}
+ *
+ * The document structure tags provide a means of specifying structural information
+ * such as headers, paragraphs, tables, and figures. The inclusion of structural information facilitates:
+ * * Extraction of text and graphics for copy and paste
+ * * Reflow of text and graphics in the viewer
+ * * Processing text eg searching and indexing
+ * * Conversion to other formats
+ * * Accessability support
+ *
+ * The list of structure types is specified in section 14.8.4 of the
+ * [PDF Reference](http://www.adobe.com/content/dam/Adobe/en/devnet/acrobat/pdfs/PDF32000_2008.pdf).
+ *
+ * Note the PDF "Link" structure tag is the same as the cairo %CAIRO_TAG_LINK tag.
+ *
+ * The following example creates a document structure for a document containing two section, each with
+ * a header and a paragraph.
+ *
+ * <informalexample><programlisting>
+ * cairo_tag_begin (cr, "Document", NULL);
+ *
+ * cairo_tag_begin (cr, "Sect", NULL);
+ * cairo_tag_begin (cr, "H1", NULL);
+ * cairo_show_text (cr, "Heading 1");
+ * cairo_tag_end (cr, "H1");
+ *
+ * cairo_tag_begin (cr, "P", NULL);
+ * cairo_show_text (cr, "Paragraph 1");
+ * cairo_tag_end (cr, "P");
+ * cairo_tag_end (cr, "Sect");
+ *
+ * cairo_tag_begin (cr, "Sect", NULL);
+ * cairo_tag_begin (cr, "H1", NULL);
+ * cairo_show_text (cr, "Heading 2");
+ * cairo_tag_end (cr, "H1");
+ *
+ * cairo_tag_begin (cr, "P", NULL);
+ * cairo_show_text (cr, "Paragraph 2");
+ * cairo_tag_end (cr, "P");
+ * cairo_tag_end (cr, "Sect");
+ *
+ * cairo_tag_end (cr, "Document");
+ * </programlisting></informalexample>
