Changes over r5.6_dev4:
A lot of reflection changes:
Further improved reflection filtering to look smoother and stay stable even when moving around,
Further improved half resolution reflections to look more consistent. Thanks to FoZy STYLE for the contribution,
Tweaked the way block reflections are applied to make reflections look more natural,
Tweaked reflections on entities and held items to look closer to regular block reflections,
Tweaked the look of carpets, snow layers, and powder snow in world space reflections,
Fixed world space reflections having some cutoff/fading point issues. Thanks to FoZy STYLE,
Fixed half resolution reflections often looking too bright or too dark around block edges,
Fixed half resolution reflections having a one pixel gap in some situations. Thanks to FoZy STYLE,
Fixed a slight performance regression regarding the new reflection filtering,
Fixed block reflections being broken on very old Optifine versions,
Fixed translucent entities or held items causing broken reflections behind them when world space reflections are enabled,
Fixed translucent blocks causing impossible reflections on nearby surfaces in some cases,
Altitude of clouds now automatically change in custom worlds that have unusual values (Iris only feature),
"IPBR+ Compatibility Mode" setting now simplifies froglight emission as well,
Fixed some lights being able to pass through tinted glass when Advanced Color Tracing is enabled,
Fixed driver-level forced anisotropic filtering causing Unbound clouds to look broken. Although it is still not recommended to use driver-level forced AF as it can cause texture glitches and bad performance,
Fixed firefly bushes having broken waving animation in some situations,
Fixed some error messages still mentioning "Advanced Colored Lighting" instead of "Advanced Color Tracing",
Small unimportant changes
