cairo-1.16.0-5.2.1

- Add 2 upstream bug fix patches:
  + cairo-Use-FT_Done_MM_Var-instead-of-free-when-available.patch:
    ft: Use FT_Done_MM_Var instead of free when available in
    cairo_ft_apply_variations. Fixes a crash when using freetype
    >= 2.9
  + cairo-composite_color_glyphs.patch: Fix a thinko in
    composite_color_glyphs. We can't just move around the contents
    of the passed-in string, we need to make a copy. This was
    showing up as memory corruption in pango.

- Update to version 1.16.0:
  + test: Free resources in pdf2png.
  + Drop skia backend.
  + Revert "Correctly decode Adobe CMYK JPEGs in PDF export".

- Update to version 1.15.14:
  + Features and Enhancements:
  - Add more FreeeType font color conversions to support
    COLR/CPAL.
  - Update test reference images against current pixman.
  + Bugs fixed:
  - 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
    (fdo#101547, CVE-2017-9814).
  - Fix assertion failure in the freetype backend (fdo#105746).
- Drop upstream fixed patches:
  + cairo-fix-assertion-failure-in-freetype-backend.patch.
  + cairo-CVE-2017-9814.patch.

- Add cairo-CVE-2017-9814.patch: Replace malloc with _cairo_malloc
  and check cmap size before allocating (boo#1049092,
  CVE-2017-9814, fdo#101547).

- Add cairo-fix-assertion-failure-in-freetype-backend.patch: Fix
  assertion failure in the freetype backend (fdo#105746).

- Update to version 1.15.12:
  + 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.
  + 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.
  + Bugs fixed:
  - Fix errors in csi-trace --help and --version options.
  - Fix a 'memory leak' in the image compositor, with
    pixman_glyph_cache_t.
  - Fix access of uninitialized memory found by valgrind
    (fdo#91271).
  - Fix improper initialization of memory in
    _cairo_ft_font_face_create_for_pattern() (fdo#105084).
  - Fix multi-monitor virtual desktop with negative coords on
    Win32 (fdo#100793).
  - Fix issues occuring with older FreeType versions.

- Modernize spec-file by calling spec-cleaner

- Add explicit pkgconfig(zlib) and (conditionalized on
  build_xcb_backend) pkgconfig(xcb-render) BuildRequires: closer
  alignment with what configure checks for.

- Update to version 1.15.10:
  + Features and Enhancements:
  - Add support for OpenGL ES 3.0 to the gl backend.
  - 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
    (fdo#90166).
  - Use UTF-8 filenames on Windows.
  + API Changes: cairo_svg_surface_set_document_unit() and
    cairo_svg_surface_get_document_unit().
  + Bugs fixed:
  - Fix regression in gles version detection.
  - Fix undefined-behavior with integer math.
  - Handle SOURCE and CLEAR operators when painting color glyphs
    (fdo#102661).
  - Convert images to rgba or a8 formats when uploading with
    GLESv2.
  - Use _WIN32 instead of windows.h to check for windows build.
  - Fix sigabrt printing documents with fonts lacking the
    mandatory .nodef glyph (fdo#102922).
  - Prevent curved strokes in small ctms from being culled from
    vector surfaces (fdo#103071).
  - Fix painting an unbounded recording surface with the SVG
    backend.
  - Fix falling back to system font with PDFs using certain
    embedded fonts, due to truncated font names (fdo#103249).
  - Fix handling of truetype fonts with excessively long font
    names (fdo#103249).
  - Fix race conditions with cairo_mask_compositor_t
    (fdo#103037).
  - Fix build error with util/font-view.
  - Fix assertion hit with PDFs using Type 4 fonts rendered with
    user fonts, due to error when destroying glyph page
    (fdo#103335).
  - Set default creation date for PDFs.
  - Prevent invalid ptr access for > 4GB images (fdo#98165).
  - Prevent self-copy infinite loop in Postscript surface.
  - Fix padded image crash in Postscript surface.
  - Fix annotation bugs in PDFs and related memory leaks.
  - Fix test failures and other assorted issues in ps and pdf
    code.
  - Fix code generation when using GCC legacy atomic operations
    (fdo#103559).
  - Fix various compilation warnings and errors.
  - Fix various distcheck errors with private symbols, doxygen
    formatting etc.
- Drop cairo-image-prevent-invalid-ptr-access.patch

- Depend on pkgconfig(gl) and pkgconfig(egl) instead of Mesa-devel.
  * The pkgconfig(gl) and pkgconfig(egl) are what cairo really
    needs. Mesa-devel is too general and is a bottleneck in
    distribution build. (bnc#1071297)

- Update to version 1.15.8:
  + This small snapshot provides new colored emoji glyph support,
    and a handful of minor fixes. For a complete log of changes,
    please see
    http://cairographics.org/releases/ChangeLog.1.15.8
  + Features and Enhancements: Support colored emoji glyphs, stored
    as PNG images in OpenType fonts.
  + Bug Fixes:
  - pdf:
    . Fix internal links pointing to other pages, by
    pre-calculating page heights so that link positions can be
    calculated more accurately.
    . Don't emit /PageLabel dict when no labels defined.
  - image: Fix crash on negative lengths.
  - win32: Fix initialization of mutexes for static builds.
  - font:
    . Fix color font loading on big-endian systems.
    . Fix color font support infinite-loop with empty glyphs.
  - Fix off by one check in cairo-image-info.c.
- Drop cairo-fix-off-by-one-check.patch: Fixed upstream.
- Run spec-cleaner, modernize spec.
- Rename 0001-image-prevent-invalid-ptr-access-for-4GB-images.patch
  to cairo-image-prevent-invalid-ptr-access.patch.
- Pass enable-gtk-doc instead of disable-gtk-doc to configure, we
  already have the gtk-doc BuildRequires in place so I can only
  assume that this was an honest error.

- Add 0001-image-prevent-invalid-ptr-access-for-4GB-images.patch to
  fix a segfault when using >4GB images since int values were used
  for pointer operations (bsc#1007255, fdo#98165, CVE-2016-9082).

- Update to version 1.15.6:
  + Detect if variable fonts have synthesized bold/italic or
    non-default variants, and use a fallback font where needed.
  + 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.
  + 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.
  + 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 text-glyph-range for quartz-font.  Use 0xFFFF instead of 0
    for invalid index tracking.
  + Fix handling of Supplementary Multilingual Plane (SMP) Unicode
    characters in quartz-font.
  + Fix various issues in the drm backend including updating API
    usage and general code cleanup.
  + Clarify documentation regarding device scale inheritance and
    the units used in cairo_surface_create_similar_image
    (fdo#99094).
- Drop cairo-pdf-fixes.patch: Fixed upstream.
- Add cairo-fix-off-by-one-check.patch: Fix off by one check in
  cairo-image-info.c (fdo#101427).

- Add cairo-get_bitmap_surface-bsc1036789-CVE-2017-7475.diff to
  fix a segfault in get_bitmap_surface due to malformed font
  (bsc#1036789, fdo#100763, CVE-2017-7475).

- Rebase cairo-pdf-fixes.patch: Add commit to fix fdo#100029.

- Add cairo-pdf-fixes.patch: Three minor pdf fixes from upstream
  git (fdo#99630).

- Fix RPM groups; update summaries.
  Remove useless --with-pic which is only for static libs.

- Update to version 1.15.4:
  + 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.
  + API Changes:
  - Added a cairo API to set up Win32 surfaces for HDC with alpha
    channels.
  - New API for added PDF functionality (see above), and new
    error status item for problems relating to PDF tagging.
  - New error status items for handling of GDI, libfreetype, and
    libpng errors, respectively.
  + 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 (fdo#89232).
  + Fix "invalidfont" error on some printers when printing PDFs
    with embedded fonts that have glyphs (such as spaces) with
    num_contours == 0 (fdo#79897).
  + Fix missing glyphs such as thin dashes, which get scaled to 0
    in userspace and thus have their drawing operations culled
    (fdo#94615).
  + Fix other oddities caused by variously idiosyncratic fonts.
  + Fix deadlock when destruction of a scaled font indirectly
    triggers destruction of a second scaled font, causing the
    global cache to be locked twice (fdo#93891).
  + Fix X errors reported to applications when shmdt() is called
    before the Attach request is processed, due to missing xcb and
    xlib calls.
  + Fix random failure in record-paint-alpha-clip-mast test case,
    caused by an incorrect assumption that a deferred clear can be
    skipped (fdo#84330).
  + Fix crash when dealing with an XShmGetImage() failure, caused
    by a double free in _get_image_surface() (fdo#91967).
  + Fix invalid execution of ASCII85 data by the PS interpreter
    that the image operator didn't use, by flushing the extraneous
    data after drawing the image (fdo#84811).
  + Fix decoding of Adobe Photoshop's inverted CMYK JPEG files in
    PDF export.
  + Fix unbounded surface assertion in win32-print code.
  + 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 (fdo#90318).
  + Cleanup debugging text sent to stdout instead of log
    (fdo#95227).
  + Fix build issue when using non-GNU strings utility (fdo#88639).
  + Fix build of cairo modules as regular modules, not as versioned
    shared libaries (fdo#29319).
  + Fix build on win32 using gcc 5.4.
  + Fix build of script backend to require zlib.
  + Update test suite reference images using Debian Jessie 64-bit
    and poppler current as of June, 2016.
  + Various improvements to documentation and tests, compiler
    warning fixes, and an assortment of code refactoring and
    cleanup.
- Drop cairo-modules-no-version.patch,
  cairo-bsc958844-deadlock-on-scaled-font-cache-reset.patch and
  cairo-xlib-double-free.patch: Fixed upstream.
- Drop libtool BuildRequires and stop passing autoreconf, we no
  longer have any patches touching the buildsystem.

- Add cairo-xlib-double-free.patch to fix double free in
  _get_image_surface(); patch taken from upstream git (fdo#91967,
  boo#997189).

- Add back cairo-bsc958844-deadlock-on-scaled-font-cache-reset.patch
  (bsc#958844, fdo#93891). This is still not fixed upstream.
