[Paraview] Getting tick marks to match data points

[Wylie, Brian]

Dave,

I actually 'fixed' the cube axes some time back. The rational behind
having the ticks 'inset' a bit is so that when two axes come to the same
endpoint the text does not overlap.

The old mode of operation was to inset the ticks and then actually show
a different value like .95 instead of 1. This pissed off most users to
no end because they couldn't actually see the true extents of their
data. I certainly believe that showing the actual end point values is
preferred...  The only question is how do you adjust the text so that is
does not overlap in a reasonable way. Probably the best solution is to
have the ticks at the end but then have the text offset enough to avoid
overlap. 

If the current mode bothers you, just enter in a feature/bug request. :)
