LLExtStatus needs to be at least of type U32 to remedy this problem, but
while at it it makes sense to turn it into what it is: An enum. Turning
it into a class enum has the added benefit we get type safety for mostly
free.
Which incidentally turned up a problem right away:
A call to removeAndCallbackPendingDownloads had status and extstatus
reversed and thus was wrong.
SL-13084: Fix clouds flipped along East/West axis to match texture preview Cloud Image and direction to match Cloud Scroll
SL-13804: Fix clouds flipped along East/West axis to match texture preview Cloud Image and direction to match Cloud Scroll
SL-13084: Fix inverted cloud scroll with ALM is off
SL-13084: Move texture coords section to top in class2/windlight/cloudsV to match class1/deffered/cloudsV
SL-13084: Add references to other common files
Remove all references to unused shader var global_gamma.
Remove many unused decls for gamma from shaders.
Make post-deferred gamma correction use display_gamma.
Make setting display_gamma use the correct RenderDeferredDisplayGamma setting.
Use rotated lightnorm directly in water shader instead of forcing all shaders marked as water (including lighting) to get that norm
(where it would only affect Mid as only that graphics mode has atmospherics on but isn't using deferred rendering).
Fix ambient light inputs to the renderer.
Fix 3rd sky shader w/ mistaken density mod conversion.
Make ambient clamp apply to all modes.
Tune ALM ambient clamp to match non-ALM.
Fix blend between reflected/refracted water maps (make less transparent)
and fix setting of water fog color alpha on low end to better match
prev behavior of setting the internal control value in that case.
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.
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 distortion map rendering in deferred mode not including underwater fog effects.
Fix distortion map rendering not including post-deferred content at all.
Fix distortion map rendering not including anything but sky when camera is underwater.
Update sun_up_factor/sunmoon_glow_factor uniforms even when sun disc isn't in use.
