// .NAME vtkVVTesting - wrapper around vtkTesting class to suit VV to diff with screenshots
// .SECTION Description
// Compare render windows or image data with a baseline image
//
// .SECTION Parameters and Usage
// The class uses vtkTesting to compare RenderWindows or ImageData with a
// baseline image file.
// The actual difference comparison is done by the vtkTesting class.
// Appropriate arguments need to be passed over to the vtkTesting class, such
// as the filename etc..
// There are two ways to use this class. In a Tcl script, you would set the
// render window or you could set the imagedata.
//
// \code
// vtkVVTesting testing
// testing SetRenderView $view
// for {set i 1} {$i < $argc} {incr i} {
// testing AddArgument "[lindex $argv $i]"
// }
// set res [ testing RegressionTest ${threshold} ]
// testing Delete
// \endcode
//
// or replace the second line in the code with
// \code
// testing SetImageData $image
// \endcode
//
// The additional arguments here should contain args as used by vtkTesting:
// -T Temp_dir -V BaselineFileName

// Description:
// Print the baseline image to the dashboard anyway, even if the test passed.
// This is useful for validation, since we have scripts that automatically
// generate baseline images.. Its just convenient sometimes to look at all
// the baselines on the dashboard. [On by default].
