55 * @defgroup Evas_GL Rendering GL on Evas
56 *
57 * Functions that are used to do OpenGL rendering on Evas. Evas allows you
58 * to use OpenGL to render to specially set up image objects (which act as
59 * render target surfaces).
60 *
61 * Below is an illlustrative example of how to use OpenGL to render to an
62 * object in Evas.
