Subject: Correct computation of intermediate axis coordinates
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=eff1313c6b7eb7bec217f7b9178857abe8c77356;p=emacs.git

Correct computation of intermediate axis coordinates

* src/sfnt.c (sfnt_compute_tuple_scale, sfnt_vary_simple_glyph)
(sfnt_vary_compound_glyph): Correct typos involving
intermediate_end (or something of the like) being set to
intermediate_start.
