+Plugin(SphericalRaise) transforms the
+coordinates of the elements in the view
+`iView' using the values associated with the
+`TimeStep'-th time step. Instead of elevating
+the nodes along the X, Y and Z axes as in
+View[`iView'].RaiseX, View[`iView'].RaiseY
+and View[`iView'].RaiseZ, the raise is applied
+ along the radius of a sphere centered at
+(`Xc', `Yc', `Zc'). To produce a standard
+radiation pattern, set `Offset' to minus the
+radius of the sphere the original data lives on.
+If `iView' < 0, the plugin is run on the current
+view.
