A billboard would work, but you would need to be very careful to draw it
at the far plane. A better way would be to create your own draw callback
in which you clear the depth buffer, disable it, draw a textured quad and
then re-enable the depth buffer. You can avoid clearing the depth buffer
if you disable the depth test and draw your quad at the far plane. I'm not
sure which way is faster.
