[vtkusers] Output precision adjustment?

[Nico Schlömer]

Hi,

as a VTK beginner, I'm not implementing my first proper VTK C++
interface library.

The plan was to store numerical data in VTK format to be able to look
at it, and also store it for later use. The latter makes it necessary
to store the data in relatively high precision (something like 1e-16),
but it seems like, e.g., vtkStructuredPointsWriter only uses a few
digits for output.

Is there any way to adjust this?

Cheers,
Nico
