*
* Unlike the traditional C++ image-based test macro (vtkRegressionTestImage),
* this templated function accepts the name of a baseline image.
* It uses the existing vtkTesting infrastructure to expand the image name
* into a full path by replacing the implied filename component of the valid
* image (specified with "-V" on the command line) with the given \a img
* value. The directory portion of the valid image path preceding is untouched.
