// .NAME vtkImageNoiseSource - Create an image filled with noise.
// .SECTION Description
// vtkImageNoiseSource just produces images filled with noise. The only
// option now is uniform noise specified by a min and a max. There is one
// major problem with this source. Every time it executes, it will output
// different pixel values. This has important implications when a stream
// requests overlapping regions. The same pixels will have different values
// on different updates.
