+      Anti-Grain Geometry (AGG) is an Open Source, free of charge
+      graphic library, written in industrially standard C++.  The
+      terms and conditions of use AGG are described on The License
+      page.  AGG doesn't depend on any graphic API or technology.
+      Basically, you can think of AGG as of a rendering engine that
+      produces pixel images in memory from some vectorial data.  But
+      of course, AGG can do much more than that.
