38  * \brief OpenGL (ES) platform interface
39  *
40  * OpenGL (ES) platform interface provides abstraction for GL context
41  * creation. A single platform may support multiple methods for creating
42  * rendering contexts (such as GLX and EGL on Linux). This is accomplished
43  * by having a list of GL context factories (m_contextFactoryRegistry).
44  *
45  * Context factory is selected on run-time using --deqp-gl-context-type
46  * command line argument. If no such argument is given, first entry
47  * is used as default.
48  *
49  * See glu::ContextFactory and glu::RenderContext for complete details
50  * on the porting layer.
51  *
52  * If your platform supports EGL and you have implemented eglu::Platform,
53  * you may enable EGL support just by registering eglu::GLContextFactory.
54  *
55  * OpenGL (ES) platform implementation is required by OpenGL (ES) tests.
56  * It is NOT required by EGL or OpenCL tests.
