eglCopyBuffers — copy EGL surface color buffer to a native pixmap
                EGLBoolean eglCopyBuffers(
               | 
              EGLDisplay display, | 
| EGLSurface surface, | |
NativePixmapType native_pixmap); | 
            
display
                
              
            Specifies the EGL display connection.
surface
                
              
            Specifies the EGL surface whose color buffer is to be copied.
native_pixmap
                
              
            Specifies the native pixmap as target of the copy.
            eglCopyBuffers copies the color buffer of
            surface to native_pixmap.
        
            eglCopyBuffers performs an implicit
            glFlush
            before it returns. Subsequent
            GL commands may be issued immediately after calling
            eglCopyBuffers,
            but are not executed until copying of the color buffer is completed.
        
            The color buffer of surface is left unchanged
            after calling eglCopyBuffers.
        
            EGL_FALSE is returned if swapping of the
            surface buffers fails, EGL_TRUE otherwise.
        
            EGL_BAD_DISPLAY is generated if
            display is not an EGL display connection.
        
            EGL_NOT_INITIALIZED is generated if
            display has not been initialized.
        
            EGL_BAD_SURFACE is generated if
            surface is not an EGL drawing surface.
        
            EGL_BAD_NATIVE_PIXMAP is generated if
            the implementation does not support native pixmaps.
        
            EGL_BAD_NATIVE_PIXMAP may be generated if
            native_pixmap is not a valid native pixmap.
        
            EGL_BAD_MATCH is generated if
            the format of native_pixmap is not compatible
            with the color buffer of surface.
        
            EGL_CONTEXT_LOST is generated if a power management
            event has occurred. The application must destroy all contexts and
            reinitialise OpenGL ES state and objects to continue rendering.
