+         fillarc   - (Intented to be a fill between the curve and chord,
+                     but gd doesn't do that) - Same as pie.
+         openarc   - Outline shape with curve and chord.
+         chord     - Straight line chord between the ends of the curve,
+                     but without showing the curve.
+         fillchord - Filled triangle between chord and center.
+         openchord - Outline triangle between chord and center.
+         pie       - Filled pie segment between curve and center.
+         fillpie   - Same as pie.
+         openpie   - Outline pie segment between curve and center.
