New description:

 implicit_plot3d allows for a region to be specified. No such option exists
 for implicit_plot. The attached patch provides this option in contour_plot
 (and therefore in implicit_plot). This is achieved using a feature of
 matplotlib: masked entries in an array are not plotted.

 Apply [attachment:trac_12813_contour_plot_region_option.patch] and
 [attachment:12813_contour_plot_doc.patch]
