+ * a given platform, and because there is also substantial repetition
+ * of specific values.
+ *
+ * Each of ints, floats, colors, and fonts is an array that stores the
+ * unique values that occur in the LookAndFeel.  intMap, floatMap,
+ * colorMap, and fontMap map from value IDs (LookAndFeel::IntID, etc.)
+ * to indexes into the value arrays.  The map arrays are of fixed
+ * length, determined by the maximum ID value.  If a value for a
+ * particular ID is not present, the entry in the map is set to -1.
