Hi Dean and Mark,

I notice this with vtkAxesActor too.

I looked back over the CVS logs for vtkTextActor since 5.0 and it looks 
like its that change alright (r1.30). vtkImageMapper isn't used though- 
the font is rendered into a vtkImageData buffer which is used to texture 
a rectangle... this allows text to be rotated.

The font size isn't always working either...
