[vtkusers] vtkTextProperty::AntiAliasingOn in 5.0+

[David Marshburn]

it seems like this (and other) anti-aliasing hint functions have gone 
away in 5.0+.  is there a recommended alternative?  or is all text 
always anti-aliased now?

(and, not just the global anti-aliasing hint, but per-object 
anti-aliasing)

thanks,
