+
+<p>The current version of <code>sketch</code> has no clipping
+<a name="index-clipping-492"></a>operations. The entire scene is always drawn. This means that when a
+perspective transform is employed, it is the user's responsibility to
+make sure the entire scene remains in front of the viewer, the region
+z&lt;0.
