+Add :rc:`contour.linewidths` to rcParams
+----------------------------------------
+
+The new config option :rc:`contour.linewidth` allows to control the default
+linewidth of contours as a float. When set to ``None``, the linewidths fall
+back to :rc:`lines.linewidth`. The config value is overidden as usual
+by the ``linewidths`` argument passed to `~.axes.Axes.contour` when
+it is not set to ``None``.
