docs: // LoadFontFace is a helper function to load the specified font file with
  // the specified point size. Note that the returned `font.Face` objects
  // are not thread safe and cannot be used in parallel across goroutines.
  // You can usually just use the Context.LoadFontFace function instead of
  // this package-level function.
