[vtkusers] Text mapper / ATI Mobility Radeon bug

[Goodwin Lawlor]

Hi All,

Just in case anyone else had this problem... the recent changes in CVS to
the text mappers cleared up the crashes occuring in the opengl drivers when
rendering some antialiased fonts with a ATI Mobility Radeon graphics card.

Here's the original thread. I had thought is was a vtkActor2D problem but
narrowed it down to antialiased font mapping.
