[PATCH 0/1] MR5893: uniscribe: Update ETO_GLYPH_INDEX flag even if script cache is freed.

[Danyil Blyschak (＠blyss)]

If the script cache was already freed before ScriptTextOut() runs and
hence the sfnt member is not available, use the definition from
init_script_cache() to conditionally apply the ETO_GLYPH_INDEX flag.
