docs: Perform any platform-specific postprocessing of `tempname`
  
          This is where Mac header rewrites should be done; other platforms don't
          have anything special they should do.
  
          Resource providers should call this method ONLY after successfully
          extracting a compressed resource.  They must NOT call it on resources
          that are already in the filesystem.
  
          `tempname` is the current (temporary) name of the file, and `filename`
          is the name it will be renamed to by the caller after this routine
          returns.
