* include/freetype/ftimage.h (FT_RASTER_FLAG_): Added
a new raster flag `FT_RASTER_FLAG_SDF'. The `ftsdf'
rasterizer will only render if this flag is set.
* src/sdf/ftsdfrend.c (ft_sdf_render): Set the `flags' field
of `FT_Raster_Params' to `FT_RASTER_FLAG_SDF'.

* src/sdf/ftsdf.c (sdf_shape_dump): Use `FT_TRACEX'
