Try it with contour also.. No errors, but no lines :-)

The issue is that the contours are in fact patch objects and not lines
so that something like "colormap cool" will change their color. In
contourf the patches FaceColor is "flat" and in contour it is "none".
Neither __go_draw_axes__.m nor __contour__.m respected the linewidth
variable. And worse, the __contourc__ function choked on the linewidth
variable generating no lines with the contour function. See the attached
patch that should fix this issue.
