  * 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.
