Hi,

When I run [CubeAxesActor2D](https://vtk.org/Wiki/VTK/Examples/Cxx/Visualization/CubeAxesActor2D) example and change the font size from

> tprop-\>SetFontSize(20);

to e.g.

> tprop-\>SetFontSize(40);

the actual font size does not change.

Any idea why/how to change label font size?

Thank you.
