For the benefit of the list, I just merged in a topic branch that simplifies
the vtkImageItem, and added a test (TestContextImage) that loads a PNG (the
VTK logo), and then displays it using vtkImageItem. I think this should
serve as a useful example of loading and displaying an image in the 2D API..
