36   * A FontInfo object holds all calculated or derived data needed
37   * to handle rendering operations based on a particular set of
38   * Graphics2D rendering attributes.
39   * Note that this does not use a Font2DHandle, and also has a reference
40   * to the strike which also references the Font2D.
41   * So presently, until SG2D objects no longer reference this FontInfo,
42   * there is still some potential for a bad Font2D to be used for a short
43   * time. I am reluctant to add the overhead of that machinery here without
44   * a proven benefit.
