Fair point.  Anyways, there is no option for that, and I won't add
one.  The patch I mentioned would be a small, namely to add the
lines

  if ( load_flags & FT_LOAD_RENDER )
  {
    load_flags &= 0xFFF0FFFFL; /* unset rendering modes */
    load_flags |= FT_LOAD_TARGET_MONO;
  }

near the beginning of `FT_Load_Glyph', and

  render_mode = FT_RENDER_MODE_MONO;

near the beginning of `FT_Render_Glyph' (untested).  Maybe there are
more spots to handle in the source code; I haven't checked this
thoroughly.
