* 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.
