/**
 * @brief Provides a set of helper functions and macros to use GLES 2.0 with
 * @ref Evas_GL "Evas GL".
 *
 * This file redefines all the OpenGL-ES 2.0 functions as follow:
 * @code
#define glFunction  __evas_gl_glapi->glFunction
 * @endcode
 *
 * Extension functions can then be checked for existence simply by writing:
 * @code
if (glExtensionFunction)
  {
     ...
     glExtensionFunction(...);
     ...
  }
 * @endcode
 *
 * When using Elementary @ref GLView, please include the header file
 * @ref Elementary_GL_Helpers "Elementary_GL_Helpers.h" instead.
 *
 * This header file should be included when using @ref Evas_GL "Evas GL"
 * directly at a low level and with an OpenGL-ES 2.0 context only.
 *
 * @note When this file is included, all @c glFunctions are now macros, which
 *       means that the @ref Evas_GL_API struct can't be used anyore.
