  Handle unsorted SFNT type 4 cmaps correctly (reported by Dirck Blaskey). * src/sfnt/ttcmap.h (TT_CMap): Add member `unsorted'. * src/sfnt/ttcmac.c: Use SFNT_Err_Ok where appropriate. (tt_cmap0_validate, tt_cmap2_validate, tt_cmap6_validate, tt_cmap8_validate, tt_cmap10_validate, tt_cmap12_validate): Use `FT_Error' as return type. (tt_cmap4_validate): Use `FT_Error' as return type. Return error code for unsorted cmap. (tt_cmap4_char_index, tt_cmap4_char_next): Use old code for unsorted cmaps. (tt_face_build_cmaps): Set `unsorted' variable in cmap. Minor formatting.
