[FFe] Sync freetype 2.4.6-2 (main) from Debian unstable (main)

Please sync freetype 2.4.6-2 (main) from Debian unstable (main)

FreeType 2.4.6[1] and 2.4.5[2] has been released, this version fixed several
issues. Also fixed broken cjk fonts renderring in evince and other software.

Highlights from changelog
    - For TrueType based fonts, the ascender and descender values were
      incorrect sometimes (off by a pixel if the ppem value was not a
      multiple of 5). Depending on the use you might now experience
      a different layout; the change should result in better, more
      consistent line spacing.

    - Fix CVE-2011-0226 which causes a vulnerability while handling
      Type 1 fonts.

    - BDF fonts containing glyphs with negative values for ENCODING
      were incorrectly rejected. This bug has been introduced in
      FreeType version 2.2.0.

    - David Bevan contributed a major revision of the FreeType stroker
      code:

      . The behaviour of FT_STROKER_LINEJOIN_BEVEL has been corrected.

      . A new line join style, FT_STROKER_LINEJOIN_MITER_FIXED, has
        been introduced to support PostScript and PDF miter joins.

      . FT_STROKER_LINEJOIN_MITER_VARIABLE has been introduced as an
        alias for FT_STROKER_LINEJOIN_MITER.

      . Various stroking glitches has been fixed.

    - A rendering regression for second-order Bézier curves has been
      fixed, introduced in 2.4.3.

    - If autohinting is not explicitly disabled, FreeType now uses
      the autohinter if a TrueType based font doesn't contain native
      hints.

    - The load flag FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH has been made
      redundant and is simply ignored; this means that FreeType now
      ignores the global advance width value in TrueType fonts.

    - Again some fixes to better handle broken fonts.

    - Just Fill Bugs contributed (experimental) code to compute blue
      zones for CJK Ideographs, improving the alignment of horizontal
      stems at the top or bottom edges.
