+%%
+%% This defines a new fill style, "gradient", for use with PSTricks,
+%% which has gradiated color. The following parameters are used:
+%%
+%%    gradbegin=color     : Beginning color.
+%%    gradend=color       : Final color.
+%%    gradlines=int       : Number of lines to use. The higher the number,
+%%                           the slower the rendering.
+%%    gradmidpoint=num    : Gradient color goes from gradbegin to gradend,
+%%                           and then back to beginning. Midpoint (point
+%%                           where "gradend" color appears, is gradmidpoint
+%%                           from the top.  (0 <= Gmidpoint <= 1).
+%%    gradangle=angle     : Rotate image by angle.
+%%    GradientCircle=true : Instead of a linear a circled gradient is build.
+%%                          (version 1.04)
+%%    GradientPos=(x,y) :   the center of the circled gradient
+%%                          (version 1.04)
+%%    GradientScale=float : scaling factor of the circled gradient
+%%                          (version 1.04)
