 * \brief OpenGL (ES) platform interface
 *
 * OpenGL (ES) platform interface provides abstraction for GL context
 * creation. A single platform may support multiple methods for creating
 * rendering contexts (such as GLX and EGL on Linux). This is accomplished
 * by having a list of GL context factories (m_contextFactoryRegistry).
 *
 * Context factory is selected on run-time using --deqp-gl-context-type
 * command line argument. If no such argument is given, first entry
 * is used as default.
 *
 * See glu::ContextFactory and glu::RenderContext for complete details
 * on the porting layer.
 *
 * If your platform supports EGL and you have implemented eglu::Platform,
 * you may enable EGL support just by registering eglu::GLContextFactory.
 *
 * OpenGL (ES) platform implementation is required by OpenGL (ES) tests.
 * It is NOT required by EGL or OpenCL tests.
