Releasing EGL Resources

Releases all resources allocated by EGL

To release the resources in the context, first the context has to be released from its binding with the current thread.

 	eglMakeCurrent(_eglDisplay, EGL_NO_SURFACE, EGL_NO_SURFACE, EGL_NO_CONTEXT);
 

Terminate the display, and any resources associated with it, including the EGLContext.

 	eglTerminate(_eglDisplay);
