Do you implement this without touching the GL driver code? Seems
difficult to avoid touching the driver in the general case, when the
format and location of pbuffer memory is intentionally opaque.

No. There is a WGL_ARB_render_texture extension but we never
finished the GLX version due to lack of interest + the expectation that
super buffers will enable similar functionality.
