Message : * src/raster/ftmisc.h: New file. Only needed if ftraster.c is compiled as stand-alone. * src/raster/ftraster.c: Add comment how to compile as stand-alone. s/FT_CONFIG_OPTION_STATIC_RASTER/FT_STATIC_RASTER/. s/TT_STATIC_RASTER/FT_STATIC_RASTER/. [_STANDALONE_]: Include ftimage.h and ftmisc.h. (FT_TRACE1, FT_TRACE6, ft_memset, FT_MEM_ZERO): Define conditionally. (Render_Glyph, Render_Gray_Glyph): Return Raster_Err_None (or Raster_Err_Unsupported). (ft_black_new) [_STANDALONE_]: Fix type of `the_raster'. (ft_black_init, ft_black_reset, ft_black_set_mode, ft_black_render): Use `ras', not `raster'. (ft_black_done): Use FT_UNUSED_RASTER. (Horizontal_Sweep_Init, Horizontal_Sweep_Step, Horizontal_Gray_Sweep_Span): Use FT_UNUSED_RASTER. * docs/CHANGES: Updated.
