  TODO: This is a workaround for a weird emscripten compiler bug. The
  matplotlib/_qhull.so extension makes function pointer calls with these
  signatures, but since nothing with that signature exists in the MAIN_MODULE,
  it can't link the SIDE_MODULE. Creating these dummy functions here seems to
  work around the problem.
