From f9128119031c9108928be3daac2838ac7c53ff7b Mon Sep 17 00:00:00 2001 From: Søren Sandmann Pedersen Date: Wed, 30 May 2012 05:19:08 -0400 Subject: Use new pixman_glyph_cache_t API that will be in pixman 0.28.0 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This new API allows glyphs to be cached in a data structure in pixman, and entire glyph strings to be composited in one go. Also bump pixman dependency to 0.27.2.
