  <summary>Security update for freetype2</summary>
  <description>This update for freetype2 to version 2.10.1 fixes the following issues:

Security issue fixed:

- CVE-2018-6942: Fixed a NULL pointer dereference within ttinerp.c (bsc#1079603).

Non-security issues fixed:

- Update to version 2.10.1
  * The bytecode hinting of OpenType variation fonts was flawed, since
    the data in the `CVAR' table wasn't correctly applied.
  * Auto-hinter support for Mongolian.
  * The handling of  the default character in PCF fonts as  introduced
    in version 2.10.0 was partially broken, causing premature abortion
    of charmap iteration for many fonts.
  * If  `FT_Set_Named_Instance' was  called  with  the same  arguments
    twice in a row, the function  returned an incorrect error code the
    second time.
  * Direct   rendering   using  FT_RASTER_FLAG_DIRECT   crashed   (bug
    introduced in version 2.10.0).
  * Increased  precision  while  computing  OpenType  font   variation
    instances.
  * The  flattening  algorithm of  cubic  Bezier  curves was  slightly
    changed to make  it faster.  This can cause  very subtle rendering
    changes, which aren't noticeable by the eye, however.
  * The  auto-hinter  now  disables hinting  if there  are blue  zones
    defined for a `style' (i.e., a certain combination of a script and
    its related typographic features) but the font doesn't contain any
    characters needed to set up at least one blue zone.
- Add tarball signatures and freetype2.keyring

- Update to version 2.10.0
  * A bunch of new functions has been added to access and process
    COLR/CPAL data of OpenType fonts with color-layered glyphs.
  * As a GSoC 2018 project, Nikhil Ramakrishnan completely
    overhauled and modernized the API reference.
  * The logic for computing the global ascender, descender, and
    height of OpenType fonts has been slightly adjusted for
    consistency.
  * `TT_Set_MM_Blend' could fail if called repeatedly with the same
    arguments.
  * The precision of handling deltas in Variation Fonts has been
    increased.The problem did only show up with multidimensional
    designspaces.
  * New function `FT_Library_SetLcdGeometry' to set up the geometry
    of LCD subpixels.
  * FreeType now uses the `defaultChar' property of PCF fonts to set
    the  glyph for  the undefined  character  at glyph  index 0  (as
    FreeType already does for all other supported font formats).  As
    a consequence, the order of glyphs of a PCF font if accessed
    with  FreeType can be different now compared to previous
    versions.
    This change doesn't affect PCF font access with cmaps.
  * `FT_Select_Charmap' has been changed to allow  parameter value
    `FT_ENCODING_NONE', which is valid for BDF, PCF, and Windows FNT
    formats to access built-in cmaps that don't have a predefined
    `FT_Encoding' value.
  * A previously reserved field in the `FT_GlyphSlotRec' structure
    now holds the glyph index.
  * The usual round of fuzzer bug fixes to better reject malformed
    fonts.
  * `FT_Outline_New_Internal' and `FT_Outline_Done_Internal' have
    been removed.These two functions were public by oversight only
    and were never documented.
  * A new function `FT_Error_String' returns descriptions of error
    codes if configuration macro FT_CONFIG_OPTION_ERROR_STRINGS is
    defined.
  * `FT_Set_MM_WeightVector' and `FT_Get_MM_WeightVector' are new
    functions limited to Adobe MultiMaster fonts to directly set and
    get the weight vector.

- Enable subpixel rendering with infinality config:

- Re-enable freetype-config, there is just too many fallouts.

- Update to version 2.9.1
  * Type 1 fonts containing flex features were not rendered
    correctly (bug introduced in version 2.9).
  * CVE-2018-6942: Older FreeType versions can crash with certain
    malformed variation fonts.
  * Bug fix: Multiple calls to `FT_Get_MM_Var' returned garbage.
  * Emboldening of bitmaps didn't work correctly sometimes, showing
    various artifacts (bug introduced in version 2.8.1).
  * The auto-hinter script ranges have  been updated for Unicode 11.
    No support for new scripts have been added, however,  with the
    exception of Georgian Mtavruli.
- freetype-config is now deprecated by upstream and not enabled
  by default.

- Update to version 2.10.1
  * The `ftmulti' demo program now  supports multiple hidden axes with
    the same name tag.
  * `ftview', `ftstring', and `ftgrid' got  a `-k' command line option
    to emulate a sequence of keystrokes at start-up.
  * `ftview', `ftstring', and `ftgrid' now support screen dumping to a
    PNG file.
  * The bytecode debugger, `ttdebug',  now supports variation TrueType
    fonts; a variation font instance can be selected with the new `-d'
    command line option.
- Add tarball signatures and freetype2.keyring

- Update to version 2.10.0
  * The  `ftdump' demo  program has new options `-c'  and `-C'  to
    display charmaps in compact and detailed format, respectively.
    Option `-V' has been removed.
  * The `ftview', `ftstring', and `ftgrid' demo programs use a new
    command line option `-d' to specify the program window's width,
    height, and color depth.
  * The `ftview' demo program now displays red boxes for zero-width
    glyphs.
  * `ftglyph' has limited support to display fonts with
    color-layered glyphs.This will be improved later on.
  * `ftgrid' can now display bitmap fonts also.
  * The `ttdebug' demo program has a new option `-f' to select a
    member of a TrueType collection (TTC).
  * Other various improvements to the demo programs.

- Remove "Supplements: fonts-config" to avoid accidentally pulling
  in Qt dependencies on some non-Qt based desktops.(bsc#1091109)
  fonts-config is fundamental but ft2demos seldom installs by end users.
  only fonts-config maintainers/debuggers may use ft2demos along to
  debug some issues.

- Update to version 2.9.1
  * No changelog upstream.
