// .NAME vtkImageDataLIC2D
//
// .SECTION Description
// GPU implementation of a Line Integral Convolution, a technique for
// imaging vector fields.
//
// The input on port 0 is an vtkImageData with extents of a 2D image. It needs
// a vector field on point data. This filter only works on point vectors. One
// can use a vtkCellDataToPointData filter to convert cell vectors to point
// vectors.
//
// Port 1 is a special port for customized noise input. It is an optional port.
// If noise input is not specified, then the filter using vtkImageNoiseSource to
// generate a 128x128 noise texture.
