[vtkusers] Precision Loss During PolyData File Manipulation

[oyster]

Hi, Thomas
The precision loss is caused by the polydatawriter, since you stored it as
ASCII. Using BINARY would cure this usually.

BTW, is you are not sure float will be as precise as it, set vtkPoints'
datatype to DOUBLE. Some vtkAlgorithm also has similar settings.

Regards,
Sancho.
