  Make `glyph_name' parameter to `FT_Get_Name_Index' a `const'. * include/freetype/freetype.h (FT_Get_Name_Index), include/freetype/internal/ftobjs.h (FT_Face_GetGlyphNameIndexFunc), include/freetype/internal/services/svgldict.h (FT_GlyphDict_NameIndexFunc), src/base/ftobjs.c (FT_Get_Name_Index), src/cff/cffdrivr.c (cff_get_name_index), src/sfnt/sfdriver.c (sfnt_get_name_index), src/type1/t1driver.c (t1_get_name_index), src/type42/t42drivr.c (t42_get_name_index): Add `const' to second argument.

     *
     * This driver implements Type42 fonts as described in the
     * Technical Note #5012 from Adobe, with these limitations:
     *
     * 1) CID Fonts are not currently supported.
     * 2) Incremental fonts making use of the GlyphDirectory keyword
     *    will be loaded, but the rendering will be using the TrueType
     *    tables.
     * 3) As for Type1 fonts, CDevProc is not supported.
     * 4) The Metrics dictionary is not supported.
     * 5) AFM metrics are not supported.
     *
     * In other words, this driver supports Type42 fonts derived from
     * TrueType fonts in a non-CID manner, as done by usual conversion
     * programs.
