[IGSTK-Developers] FourViewsTrackingWithCT Application

[Patrick Cheng]

Hi Julien,

I don't think it's neccessary to make an itkTextSpatialObject, if we are 
only going to have a string representation of the text. Unless we are 
going to generate a polygon representation, like vtkTextSource.

I think we can just use the vtkTextSource in the igstkTextSpatialObject 
without having a corresponding itkTextSpatialObject.

What do you think?
