How can I set the font size of the `TitleTextProperty` of a `vtkCubeAxesActor`?
The code below does not result in the specified font size of the `vtkCubeAxesActor` when plotting.
`import vtk`
`ca = vtk.vtkCubeAxesActor()`
`ca.GetTitleTextProperty(0).SetFontSize(48)`

There’s a workaround for this:
```auto
font_size = 48
import vtk
ca = vtk.vtkCubeAxesActor()
ca.SetScreenSize(font_size / 12 * 10.0)
```
