  [autofit] Add bluezones for CJK Ideographs.
  
  To remove extremas of vertical strokes of CJK Ideographs at
  low resolution and make the top and bottom horizontal stems
  aligned, bluezones for CJK Ideographs are calculated from
  sample glyphs.  At present, vertical bluezones (bluezones
  to align vertical stems) are disabled by default.  For detail, see

  * include/freetype/internal/fttrace.h: New trace component `afcjk'.
  * src/autofit/afcjk.h (AF_CJK{Blue,Axis,Metric}Rec): Add CJK version
  for AF_Latin{Blue,Axis,Metric}Rec.
  (af_cjk_metrics_check_digits): Ditto, shared with Indic module.
  (af_cjk_metrics_init_widths): Ditto.
  (af_cjk_metrics_init): Take AF_CJKMetric instead of AF_LatinMetric.
  (af_cjk_metrics_scale): Ditto (declaration).
  (af_cjk_hints_init): Ditto (declaration).
  (af_cjk_hints_apply): Ditto (declaration).
  * src/autofit/afcjk.c (af_cjk_metrics_scale): Ditto (body).
  (af_cjk_hints_init): Ditto (body).
  (af_cjk_hints_apply): Ditto (body).
  (af_cjk_metrics_init_widths): Duplicate af_latin_metrics_init_widths.
  (af_cjk_metrics_check_digits): Duplicate af_latin_metrics_check_digits.
  (af_cjk_metrics_init): Call CJK bluezone initializer.
  (af_cjk_metrics_scale_dim): Add code to scale bluezones.
  (af_cjk_hints_compute_blue_edges): New function, CJK version of
  af_latin_hints_compute_blue_edges.
  (af_cjk_metrics_init_blues): New function, CJK version of
  af_latin_metrics_init_blues.
  (af_cjk_hints_edges): Add code to align the edge stems to blue zones.
  
  * src/autofit/afindic.c (af_indic_metrics_init): Take AF_CJKMetric
  instead of AF_LatinMetric, and initialize as af_cjk_metrics_init.
  However bluezones are not initialized.
  (af_indic_metrics_scale): Take AF_CJKMetric instead of AF_LatinMetric.
