[vtkusers] Cross platform rendering tests

[Ken Martin]

To drive the testing take a look at testing with ctest

To do image comparisons look at vtkRegressionTestImage.h and vtkTesting.h
We typically invoke testing as

  int retVal = vtkRegressionTestImage( renWin );

The typical approach uses argc and argv to extract the location of a valid
image file to use as a comparison. Those two headers have some example code
in them. We test nightly on OSX, Window, and Linux with both Mesa and
native drivers from Intel, Nvidia, and AMD.
