Subject: Provide access to PangoLayout.n_chars
X-Git-Tag: 1.29.1~22
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ff16b948572c1bdc301d27af41b34566d28c6610;p=platform%2Fupstream%2Fpango.git

Provide access to PangoLayout.n_chars

This lets us avoid a bunch of g_utf8_strlen() calls, when
Pango is already maintaining this information anyway.
