SL-9996, SL-1130, SL-5546

Fix bug with setting texture matrix for rigged mesh.

Fix z-fighting between sea and sky in ALM by cheating sky, stars, and moon using gl_FragDepth.

Fix handling of atmospheric haze glow w.r.t independent sun/moon positioning
(we can no longer depend on them being mutex to each other).
