[vtkusers] How-To zoom text annotations in the scene?

[Veerapuram Varadhan]

Hi All,

I have loaded a 3D volume and added few text annotations, basically, text
actors.  When I perform Zoom, my image data (3D volume or even a single
slice of that volume) gets zoomed but not my text annotations.

Is there a way that I can set my text actors to zoom as well along with
others?

TIA,

V. Varadhan.
