[Paraview] Bug report: tube diameter in paraview 4.01

[Moreland, Kenneth]

I figured it out. The problem is that to point coordinates in your data
files are integers instead of floating points. The tube filter is
inheriting the int storage for point coordinates and then rounding to the
nearest integer. This must have been a change in VTK somewhere between
ParaView 3.98 and 4.0.1 (probably to correctly inherit the float/double
precision of point coordinates).

The problem fixes itself if you change the point coordinates of your input
to be floating point numbers. I've attached modified versions of the two
data files that work correctly.
