            * one as CENTER_HORIZONTAL.
            *
            * For example:
            *    series1: none
            *    series2: VERTICAL
            *    series3: none
            *    series4: HORIZONTAL
            * JfreeChart can render none as none, but can implement only one of the gradient
            * styles defined for bar2 and bar4. In our implementation we are accepting the first
            * not-none gradient type and then rendering bar2 and bar4 with VERTICAL.
            *
            *  Check for specific renderer instances since only certain specific renderers allow
            *  setting gradient paint transform.
