+This operation acts on polygons and applies polygon smoothing with the tolerance d. 'keep_hv' indicates
+whether horizontal and vertical edges are maintained. Default is 'no' which means such edges may be distorted.

 The "smoothed" method is available as a plain function or as a method on <a href="/about/drc_ref_drc.xml">DRC</a> expressions.
 The plain function is equivalent to "primary.smoothed".

+<p>
+This method returns a new source representing the transformed layout. It is provided in the spritit of 
+<a href="/about/drc_ref_source.xml#clip">Source#clip</a> and similar methods.
+</p><p>
+The transformation
+is either given as a <class_doc href="DTrans">DTrans</class_doc>, <class_doc href="DVector">DVector</class_doc> or <class_doc href="DCplxTrans">DCplxTrans</class_doc> object or as one of the 
+following specifications:
+</p><p>
+<ul>
+<li>"shift(x, y)": shifts the input layout horizontally by x and vertically by y micrometers
+<li>"rotate(a)": rotates the input layout by a degree counter-clockwise
+<li>"magnify(m)": magnifies the input layout by the factor m (NOTE: using fractional scale factors may result in small gaps due to grid snapping)
+<li>"mirror_x": mirrors the input layout at the x axis
+<li>"mirror_y": mirrors the input layout at the y axis
+</ul>
+</p><p>
+Multiple transformation specs can be given. In that case the transformations are applied right to left.
+Using "global_transform" will reset any global transformation present already.
+Without an argument, the global transformation is reset.
