[Paraview] Show custom cube axes annotations

[Felipe Bordeu Weldt]

Ok,

My idea is simple (http://www.paraview.org/Bug/view.php?id=13583).
We visualizes data with non convectional axes, so we put that  
information (name and units) in the labels. Also we want to be able to  
use the transformation filter to modified the meshes, and we want the  
axis and labels to follow the transformation. So I'm writing a filter  
(vtkTransformWithAxis) that apply the transform to the mesh and to all  
the data that is used for the cube axis.

But I'm not able create correctly the OrientedBoundingBox and the  
three vectors to generate the Non Orthogonal Bounding Box.

So if the input does not have all the data for the axis, it will  
generate the data (vector, OriendedBoundigBox... and so on ) , and  
then apply the transformation filter.

Is that clearer?

Thanks for you time so far.
Felipe
