The \lstinline!FillPattern! attributes \lstinline!Horizontal!, \lstinline!Vertical!, \lstinline!Cross!, \lstinline!Forward!, \lstinline!Backward! and \lstinline!CrossDiag! specify fill patterns drawn with the line color over the fill color.

The attributes \lstinline!HorizontalCylinder!, \lstinline!VerticalCylinder! and \lstinline!Sphere! specify gradients that represent a horizontal cylinder, a vertical cylinder and a sphere, respectively.
The gradient goes from line color to fill color.
The gradients colors are defined considering full rectangles (ignoring rounded corners) and full ellipses (ignoring arcs).
For polygons the gradients are defined on the enclosing rectangle (for \lstinline!HorizontalCylinder!, \lstinline!VerticalCylinder!) or ellipse (for \lstinline!Sphere!).
The color gradient attains the fill color at the center, and attains the line color at two of the sides of the rectangle or the border of the ellipse.

The border pattern attributes \lstinline!Raised!, \lstinline!Sunken! and \lstinline!Engraved! represent frames which are rendered in a tool-dependent way --- inside the extent of the filled shape.
