[vtkusers] Positioning titles within vtkAxis

[Eric E. Monson]

Hey Daniel,

It does seem like SetLineOffset should do something like what you want, but I think they way the label text is applied with VerticalJustification probably nullifies any line offset setting. Line spacing shouldn't matter for a single line of text.

So, the adjustments you want are just not implemented. Marcus, the developer, has worked hard to get the labels right, though, so if you have a use case where the labels are running into the axis ticks maybe you should describe the situation and send a screen shot – it may be something that needs fixing. 

You're right that the charts are still under development, but some of the core functionality has settled down, and as you said, the current implementation is better than the 5.6.1 version.
