[Paraview] Show custom cube axes annotations

[Sebastien Jourdain]

Hi Felipe,

if you check "Use Custom Range" the cube axis will use the oriented bounds
correctly for the labels instead of using the world space coordinate bounds.
This happen by adding new field data providing the min/max for each axis
that should be used for the labels.

Regarding you question the end points of the cube axes will be

Pmin = U*OrientedBounds[0] + V*OrientedBouds[2] + W*OrientedBouds[4]
...
Pmax = U*OrientedBounds[1] + V*OrientedBouds[3] + W*OrientedBouds[5]

Hope that help,

Seb
