 * @defgroup Evas_GL Rendering GL on Evas
 * @ingroup Evas_Canvas
 *
 * @brief This group discusses the functions that are used to do OpenGL rendering on Evas. Evas allows you
 *        to use OpenGL to render to specially set up image objects (which act as
 *        render target surfaces).
 *
 *
 * <h2> Evas GL usage example </h2>
 *
 * Below is an illustrative example of how to use OpenGL to render to an
 * object in Evas.
