Add directory names to sentinels in shaders so shaders with same filename can be differentiated in nSight while debugging.

Don't re-range density multiplier twice.

Make fullbright transport look closer to normal transport so fullbright objects reflect distance.

Fix use of density and distance multipliers in atmospherics to use original pre-EEP range instead of FS expanded range.

Modify additive calc to restore old behavior (probably reverts fix for "lens flare" bug).

Make moon disc image render only if current or previous textures are available.

Tweak forced frag depths for sun/moon disc images to resolve depth fighting with hills etc.

Scale down of bloom was off by a factor of 3 or so.

Fix up shadow sampling and tweak shadow biasing.

Clean up shader decls of unused funcs.

Clean up whitespace diffs from release.

New fix for 925/926 that doesn't cause 896 again.

Also linearize moon disc tex color.

Given that mShaderObjects only ever expects one copy of a given shader object (leading to lots of "shaderV" and "shaderF"), it made having utility shaders a bit more difficult to incorporate.
This change makes sure the two are separated.  Using this over a multimap largely for readibility.

Also, actually, you know, use this functionality.

Still some work to go here.  Largely related to how certain values (i.e., SSAO mix values) are supplied.  But so far, so good.

Fix falloff on projectors in forward rendering (different falloff calcs than deferred).

Restore letting env auto-update sunlight_color uniform (other shaders expect it even if lighting does not).

Make projector ambiance unshadowed in both forward and deferred for consistency.

Fix conversion of star brightness, density mult, and distance mult to legacy ranges.

Make settings look in both legacyhaze and top-level settings for haze params.

Add decls for intermediate lighting values for debug.

Fix deferred water soften prog lightnorm getting stomped with rotated lightnorm,
because it's a water shader and needs water atmo uniform values,
but it's a deferred lighting shader that needs not-so-rotated lightnorms.

Make sunlight_color not get auto-updated so we can get the correct value from mSunDiffuse.

Remove mix to preserve bumps as it was washing out shadows.

Fix directionality of da and preserve bumps on completely shadowed areas.

Clamp far_clip for sun shadows to >= 256.0 to prevent issues when draw distance < ~100m.

Clamp ambient to keep shadows dark.

Apply min with shadow value after we've pow'd by light gamma consistently between forward and deferred.

Clamp ambient contrib to get darker shadows.

New PCF sampling func.

Disable occlusion culling when rendering water reflection/refraction maps again (still getting probabalistic results for reflection map contents). :/
