   cogl 1.22.8 (3D graphics rendering library)

   Cogl is a small open source library for using 3D graphics hardware
   for rendering. The API departs from the flat state machine style
   of OpenGL and is designed to make it easy to write orthogonal
   components that can render without stepping on each others toes.
