Subject: SL-17472 Add checkbox to preferences for enabling "PBR" that uses
 "class3" deferred shaders.  Move reflection probe shaders to class3 and
 restore class2 shaders to non-reflection probe versions.

Subject: SL-19203 et al -- Integrate SSR with reflection probes, tweak probe
 blending. (#63)

* SL-19203 WIP -- Integrate SSR with reflection probes.  Decruft LLRenderTarget.

* SL-19203 WIP -- Re-integrate SSR.  Incidental decruft.

* SL-19203 WIP -- SSR frame delta correction (still broken for Z)

* SL-19203 WIP -- SSR frame delta Z fix

* SL-19203 WIP -- Make SSR toggleable again and disable SSR in cube snapshots.

* SL-19203 WIP -- Soften sphere probe transitions and fix reflections on void water (make fallback probe a simple terrain+water+sky probe).  Remove parallax correction for automatic probes to reduce artifacts.

* SL-19203 Tune probe blending.

* SL-19203 Cleanup.

Subject: DRTVWR-559 Quality pass -- Fix sky banding, fix off-by-one-mip in
 reflection probes (thanks Rye), remove noiseMap from light shaders (removes
 speckles), make irradiance maps RGB16F instead of RGBA16.  Use actual
 luminance for sky instead of max color component during irradiance map pass.

Subject: DRTVWR-559 Revert skies to be very close to release and disable tone
 mapping when probe ambiance is zero.

Hack for desaturating legacy materials has been removed for performance and quality reasons.

Adds a new setting for auto adjusting legacy skies.  This is the PBR "opt out" button.  If disabled, legacy skies will disable tonemapping, automatic probe ambiance, and HDR/exposure.  If enabled, legacy skies will behave as if probe ambiance and HDR scale are 1.0, and ambient will be cut in half.

HDR scale will act as a sky brightener, but will automatically adjust dynamic exposure so the sky will be properly exposed.  If you want relatively even exposure all the time, set HDR Scale to 1.0.  If you want a high range of exposures between indoor/dark areas and outdoor/bright areas, increase HDR Scale.

Also tuned up SSAO (thanks Rye!).

Reviewed with Brad.
