commit eef5c1dd1455208dee1a6378016f018c8a69be35
Author: Werner Lemberg <address@hidden>
Commit: Werner Lemberg <address@hidden>
[woff2] Fix compiler warnings.
* src/sfnt/sfwoff2.c (read_num_hmetrics): Remove unused argument
`table_len'.
Update caller.
(triplet_decode, compute_bbox, store_loca, reconstruct_glyf): Make
`i' variable unsigned.
(reconstruct_glyph): Remove condition which is always false.
(reconstruct_html): Removed unused argument `transformed_size'.
Update caller.
* src/sfnt/woff2tags.c (woff2_known_tags): Remove condition which is
always false.
