This was an ill-advised extension. While we advertised SWAP_COPY support, we might implement it with a back-copy from the front buffer. And we never advertised EXCHANGE because we couldn't guarantee it. So, if you actually used this extension to try to reduce app redraws of the back buffer, you might actually increase the bandwidth you used. Whoops. Instead, GLX_EXT_buffer_age and the similar EGL extension give you feedback on what's left in your back buffer, letting you do minimum redraws. This reduces our GLX visual+fbconfig count from 1410 to 940 on an llvmpipe X server. Reducing visual counts will improve test runtime for visual-iterating tests like piglit's glx-visuals-*.
