[vtkusers] [vtkDistanceWidget] 2D point handle does not follow mouse interaction

[sonogi1979 at live.jp]

Hi,

In use of a 2D widget such as vtkDistanceWidget +
vtkDistanceRepresentation2D, the point handles are fixed on the display
position even when the view is zoomed, spun, or etc. after the handles are
moved by mouse interaction. Meanwhile, axis actor follows such mouse
operations.

The reason is the world position of the point handle is not updated in
vtkPointHandleRepresentation2D::Translate. But, distance widget uses world
position to draw the axis actor (c.f. ctor of vtkDistanceRepresentation2D).

Is it bug or designed?

Thanks,
Shinya
