+   *   Often they provide the preferred size, but not the minimum size.
+   *   This function can be used to roughly compute the minimum size based on the preferred one.
+   *   The returned size will be reduced by the difference between the full text width and
+   *   the width of the text contracted to just the {@code nCharactersToKeep} first characters plus {@code "..."}
+   *   that's usually added by such components when the text doesn't fit.
+   * </p>
+   * <p>
+   *   Note that, due to various factors, the result may be off by a few pixels which is enough to gain or lose an extra character.
+   *   Because of fractional font metrics, fractional scaling, complicated calculations, rounding errors and other such things
+   *   it's hard to make strict guarantees here.
