+rendering, manipulation, arbitrary polygon support, etc.
+
+It does ALL of these operations FAST.  Imlib2 also tries to be highly
+intelligent about doing them, so writing naive programs can be done easily,
+without sacrificing speed.
+
+This is a complete rewrite over the Imlib 1.x series.  The architecture is
+more modular, simple, and flexible.")
