Fix gcc 4.6 compiler warnings.

Browse Source 
* src/autofit/afcjk.c (af_cjk_metrics_init_blues): Use casts and
remove unused variables.
* src/autofit/aflatin.c (af_latin_hints_compute_edges): Comment out
`up_dir'.
* src/smooth/ftsmooth.c (ft_smooth_render_generic): Use `height_org'
and `width_org' conditionalized.
