[vtkusers] vtkImageReslice axes direction, based on a vtkPlane

[David Gobbi]

Hi Tijmen,

If you are able to grab the devel version of VTK from git, your
best option is to use the new image rendering classes:
http://www.vtk.org/Wiki/VTK/Image_Rendering_Classes
The vtkImageResliceMapper has a method called SetSlicePlane(),
so all you have to do is set the image as the input, then set the
plane you want to slice with.  The mapper will do everything else.
