[vtkusers] Problems with massProperties at getting area from ContourWidget

[Rodrigo Lovera]

I 'd do it with some button and shown in a label once I got the code to my
qtvtk project. I have one more question and these 'd be on how does it
measure the area, the dimensions are in pixels or mm2 maybe?? how can I
know that and maybe even set that?
