The default is bilinear filtering as before, but nearest-neighbor filtering can now be chosen for a retro look.

This affects sky radiance map and ReflectionProbe specular light.

This also marks additional settings as requiring a restart, as noticed during testing.

Testing project: test_reflection_nearest_neighbor.zip
