## Description:

This update for freetype2 fixes the following issue:

Update to freetype2 2.14.2:

  * CVE-2026-23865: Integer overflow in the tt_var_load_item_variation_store
    function (bsc#1259118).

Changelog:

  * Several changes related to LCD filtering are implemented to achieve better
    performance and encourage sound practices.
  * Instead of blanket LCD filtering over the entire bitmap, it is now applied
    only to non-zero spans using direct rendering. This speeds up the ClearType-
    like rendering by more than 40% at sizes above 32 ppem.
  * Setting the filter weights with FT_Face_Properties is no longer supported.
    The default and light filters are optimized to work with any face.
  * The legacy libXft LCD filter algorithm is no longer provided.
  * The italic angle in `PS_FontInfo` is now stored as a fixed-point value in
    degrees for all Type 1 fonts and their derivatives, consistent with CFF
    fonts and common practices. The broken underline position and thickness
    values are fixed for CFF fonts.
  * The `x` field in the `FT_Span` structure is now unsigned.
  * Demo program `ftgrid` got an option `-m` to select a start character to
    display.
  * Similarly, demo program `ftmulti` got an option `-m` to select a text string
    for rendering.
  * Option `-d` in the demo program `ttdebug` is now called `-a`, expecting a
    comma-separated list of axis values. The user interface is also slightly
    improved.
  * The `ftinspect` demo program can now be compiled with Qt6, too.
  * The auto-hinter got new abilities. It can now better separate diacritic
    glyphs from base glyphs at small sizes by artificially moving diacritics up
    (or down) if necessary
  * Tilde accent glyphs get vertically stretched at small sizes so that they
    don't degenerate to horizontal lines.
  * Diacritics directly attached to a base glyph (like the ogonek in character
    'ę') no longer distort the shape of the base glyph
  * The TrueType instruction interpreter was optimized to produce a 15% gain in
    the glyph loading speed.
  * Handling of Variation Fonts is now considerably faster
  * TrueType and CFF glyph loading speed has been improved by 5-10% on modern
    64-bit platforms as a result of better handling of fixed-point
    multiplication.
  * The BDF driver now loads fonts 75% faster.
