Changing precision for debug output is one thing, but changing it for
*.vtk file output is another, where keeping the precision is
important.

Thinking about it, the default debug output for a matrix should
probably still contain the full precision, so you don't think there's
a value exactly zero in the matrix when there really isn't. If you
need a "pretty printed" matrix, I'd suggest another method. e.g.
vtkTable::Dump(int width) dumps a table to standard output keeping
each column to a certain number of characters.
