[Paraview] Problems with the new color legend

That is by design.  The min/max labels are placed where they can be shown
with the maximum amount of precision (so that you get the most accurate
account of what the range is).

The field is working, but it really means the maximum number of (non
min/max) labels.  It will show less if it means the labels will be more
readable.  You have to bump up the number of labels to 11 before you get to
the next increment that the color bar will allow.  I changed the label next
to the field to better reflect what it means.

Note that the point of the changes to the scalar bar are to make it more
readable.  Even with only 5 labels, you can quickly pinpoint the color
precisely to the thousands place using the minor tick marks.  That's way
better than you could with the old labels.
