 In many drawing applications, the user can both manually digitize points
 and specify coordinates or offsets for adding points to the current
 drawing.

 Examples from ArcGIS Desktop:
  * insert at
 [http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#/at_an_exact_x_y_location_absolute_x_y/001t00000051000000/
 x/y]
  * insert at
 [http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#/relative_to_the_location_of_the_last_vertex_delta_x_y/001t0000005p000000/
 delta x/y]
  * insert at
 [http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#/and_a_length/001t00000063000000/
 direction/length]
  * constrain
 [http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#/from_another_segment_deflection/001t00000064000000/
 deflection]

 In addition to these methods, it is useful to be able to finish a sketch
 without double-clicking (allowing the sketch to be completed without
 adding the point currently under the mouse) and cancel a sketch
 altogether.
