X-Git-Url: http://git.chise.org/gitweb/?a=commitdiff_plain;h=113b3da29e3055d27d4c81feb0f32fef61c0eb24;p=m17n%2Fm17n-lib.git

Adjusted for the change of MGlyph.
(mfont__init): Don't call mfont__flt_init.
(mfont__fini): Don't call mfont__flt_fini.
(mfont__get_glyph_id, mfont__get_metrics): New functions.
