If OpenGL ES is requested, this hint is ignored. By default, OpenGL uses the framebuffer as a rendering destination that is created and managed entirely by the window system. However, a renderbuffer object can not be directly read from. These buffers occupy video memory like any other OpenGL object, but so far we've had little control over them besides specifying the pixel formats when you created the OpenGL context. e.
