// .NAME vtkMimxImageActor - a 3D non-orthogonal axes representation
// .SECTION Description
// vtkMimxImageActor is the abstract base class for all the pipeline setup for
// different types of datatypes. Data types concidered are vtkPolyData,
// vtkStructuredGrid (both plane and solid) and vtkUnstructuredGrid.
