* include/freetype/internal/tttypes.h (TT_SBit_MetricsRec): Widen fields to FT_Short and FT_UShort, respectively. (TT_SBitTableType): New enumeration. (TT_FaceRec): Add `sbit_table_type' field. * include/freetype/tttags.h (TTAG_sbix): New macro. * src/sfnt/pngshim.c (Load_SBit_Png): Pass a more generic FT_GlyphSlot argument instead FT_Bitmap. Add flag to control map and metrics handling. Update all users. * src/sfnt/ttsbit.c: Include `ttmtx.h'. (tt_face_load_eblc): Renamed to... (tt_face_load_sbit): This. Handlic `sbix' bitmaps. (tt_face_free_eblc): Renamed to... (tt_face_load_sbit): This. Updated. (tt_face_load_strike_metrics): Handle `sbix' bitmaps. (tt_face_load_sbix_image): New function. (tt_sbit_decoder_alloc_bitmap, tt_sbit_decoder_load_image, tt_sbit_decoder_load_byte_aligned, tt_sbit_decoder_load_bit_aligned, tt_sbit_decoder_load_compound, tt_sbit_decoder_load_png, tt_sbit_decoder_load_image, tt_sbit_decoder_load_bitmap): Don't pass and handle load flags. (tt_sbit_decoder_load_bitmap) [!FT_CONFIG_OPTION_USE_PNG]: Better handle formats 17-19. Move color to grayscale conversion to... (tt_face_load_sbit_image): Here. Handle `sbix' bitmaps. * src/sfnt/pngshim.h: Updated. * src/sfnt/ttsbit.h: Updated. * src/sfnt/sfdriver.c: Updated.
