Subject: (visual_order): Allocate one more elements for arrays as
X-Git-Tag: REL-1-1-0~60
X-Git-Url: http://git.chise.org/gitweb/?a=commitdiff_plain;h=fcd0d6b7c0a7b71b07d5019b996cbefec6287cdf;p=m17n%2Fm17n-lib.git

(visual_order): Allocate one more elements for arrays as
a workaround of fribidi bug.
(layout_glyphs): Fix previous change. Check MGlyph->combining_code
instead of MGlyph->bidi_sensitive.
(layout_glyph_string): Pay attentinon to
control->orientation_reversed when padding at the head or tail.
Fix adjustment of space glyph width.
