[vtk-developers] vtkAxesActor bug with SetUserTransform

[pat marion]

If you create a vtkAxesActor and then call this method...

void SetUserTransform<http://www.vtk.org/doc/nightly/html/classvtkProp3D.html#ac7f621f0a3666a29d21b5087919797a>(
vtkLinearTransform<http://www.vtk.org/doc/nightly/html/classvtkLinearTransform.html>*transform)

...the axis labels will be oriented correctly but not translated with the
axes.  I want to make sure this is a bug and not a "feature" that somebody
relies on.  Here is a fix I could commit:
