Powei Feng 749b03ed2a utils: refactor getopt into utils namespace (#9796 )

On certain linux, macOS environment, there is already a system

Here we alias utils::getopt to either the system getopt (if
present) or third_party/getopt.

Fixes #7551

Roughness Prefilter

roughness_prefilter is a simple tool that can be used to generate a pre-filtered roughness map from a normal map. The input roughness can either be a constant or a roughness map. The output can be used to reduce shading aliasing.
