/**
 * Describes font size hints used by the JGoodies Windows look&feel; future
 * implementations of the Plastic l&f will use the same hints. In 1.3
 * environments the sizes are used as absolute font sizes, in 1.4 environments
 * size deltas are used between SYSTEM and the specified sizes.<p>
 * 
 * NOTE: This is work in progress and will probably change in the
 * next release, to better reflect the font choice in the J2SE 1.4.1.
 * Currently, the size delta is used only for the Tahoma font!<p>
 * 
 * In 1.3 environments, the font guess is Tahoma on modern Windows,
 * "dialog" otherwise. In 1.4 environments, the system fonts will be used.
