　　昨天无意中看到2.13.0正式发布，今天专门下载下来准备整合。

　　看了一下，欣喜的发现我司提交的代码已正式启用！一方面是我司技术力量强大的体现，另外也是为开源贡献自己的力量。

  FT_GlyphSlot_Oblique( FT_GlyphSlot  slot )
  
    /* Value '0x0366A' corresponds to a shear angle of about 12 degrees. */
    FT_GlyphSlot_Slant( slot, 0x0366A, 0 );
  


  /* documentation is in ftsynth.h */

      return;

    outline = &slot->outline;

    /* only oblique outline glyphs */
    if ( slot->format != FT_GLYPH_FORMAT_OUTLINE )
      return;

    /* we don't touch the advance width */

    /* For italic, simply apply a shear transform */
    transform.xx = 0x10000L;
    transform.yx = -yslant;

    transform.xy = xslant;
    transform.yy = 0x10000L;

    FT_Outline_Transform( outline, &transform );
