// .NAME vtkConvertSelectionDomain - Convert a selection from one domain to another
//
// .SECTION Description
// vtkConvertSelectionDomain converts a selection from one domain to another
// using known domain mappings. The domain mappings are described by a
// vtkMultiBlockDataSet containing one or more vtkTables.
//
// The first input port is for the input selection (or collection of annotations
// in a vtkAnnotationLayers object), while the second port
// is for the multi-block of mappings, and the third port is for the
// data that is being selected on.
//
// If the second or third port is not set, this filter will pass the
// selection/annotation to the output unchanged.
//
// The second output is the selection associated with the "current annotation"
// normally representing the current interactive selection.
