+ * This implementation of FxData will read a the default configuration
+ * file. The values used for shadow are frouped under "FX".
+ *
+ * The values are:
+ *  Shadow.Algorithm:      the algorithm used for making the sahdow
+ *  Shadow.Scale	   the normailsation factor for veraging the sum
+ *  Shadow.MaxOpacity	   the maximum allowable opacity (255 = 100%opaque)
+ *  Shadow.OffsetX	   the X-coordinate offset (0 centered)
+ *  Shadow.OffsetY         the Y-coordinate offset (0 centered)
+ *  Shadow.Thickness	   the shadow thickness (usually 3-5 px)
+ *  Shadow.SelectionType   the selection type - inverse video or use
+ *			   the selection colours.
