[vtkusers] vtkCubeAxesActor2D size of labels when resizing window

[Hagen Mölle]

Hallo,

I am using a vtkCubeAxesActor2D in a scene. The scene gets repainted 
whenever I resize the window containing the scene. So far so good. My 
problem is the labels of the vtkCubeAxesActor2D are resized too. For 
example if my window is as big as half the screen size the visibility of 
the labels is good. If I make the window smaller the labels get to 
small. If I make the window bigger (fullscreen) the labels get to big.

Is it possible to fix the label size of vtkCubeAxesActor2D when resizing 
the window.
