[PATCH 15/21] glamor: Add glamor_program based poly_text and image_text
Keith Packard
keithp at keithp.com
Tue Apr 1 17:29:14 PDT 2014
Accelerates text painting with GPU-based geometry computation and stippling
v2: Simplify get_glyphs, expand single character variable names to
more descriptive ones. (Markus Wick)
