62 * @defgroup Evas_GL Rendering GL on Evas
63 *
64 * Functions that are used to do OpenGL rendering on Evas. Evas allows you
65 * to use OpenGL to render to specially set up image objects (which act as
66 * render target surfaces).
67 *
68 * Below is an illlustrative example of how to use OpenGL to render to an
69 * object in Evas.
