commit 7f00fa64627bb57042ec62aa2ec938f679e097c1
Author: Werner Lemberg <address@hidden>
Commit: Werner Lemberg <address@hidden>
[autofit] Improve tracing.
* src/autofit/afhints.c (af_print_idx, af_get_segment_index,
af_get_edge_index): New functions.
(af_glyph_hints_dump_points): Remove unnecessary `|', `[', and `]'.
Add segment and edge index for each point.
Slightly change printing order of some elements.
Don't print `-1' but `--' for missing elements.
(af_glyph_hints_dump_segments, af_glyph_hints_dump_edges): Remove
unnecessary `|', `[', and `]'.
Don't print `-1' but `--' for missing elements.
