  baseline level will be aligned with the {@code (x, y)} point.

  Note that you can make use of the {@link SVGHints#KEY_TEXT_RENDERING}
  hint when drawing strings (this is completely optional though).
  
  @param str  the string ({@code null} not permitted).
  @param x  the x-coordinate.
  @param y  the y-coordinate.
