That's correct. OpenGL uses two buffers; one that is currently "bound"
to the window (i.e., what you're currently looking at) and one that is
rendered into (i.e., the back buffer). When a frame finishes rendering,
the OpenGL glue calls glx_SwapBuffers() which turns the back buffer into
the bound one and turns the bound one into the back buffer.
