+% Multiplier of the radii. This is no-op in linear mode.
+% Default value: |1.2|
+% \item[\texttt{withshadingcenter} \meta{pair}]
+% Values for shifting starting center.
+% For instance,
+% |(0,0)| means that center of starting circle is |center p|;
+% |(1,1)| means |urcorner p|.
+% \item[\texttt{withshadingtransform} \meta{string}]
+% where \meta{string} shall be |"yes"| (respect transform) or |"no"| (ignore transform).
+% Default value: |"no"| for pictures made by |infont| operator; |"yes"| for all other cases.
+% \item[\texttt{withshadingdomain} \meta{pair}]
+% Limiting values of parametric variable
+% that varies on the axis of color gradient.
+% Default value: |(0,1)|
+% \item[\texttt{withshadingstep (...)}]

+% \item[\texttt{withshadingfraction} \meta{number}]
+% Fractional number of each shading step.
+% Only meaningful with |withshadingstep|.
+% \item[\texttt{withshadingcolors (}\emph{color expr}, \emph{color expr}\texttt{)}]
+% Starting and ending colors.
+% Default value: |(white,black)|
