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