[vtkusers] Text annotations in 3D window

[Wayne Christopher]

What I mean is, I would like the text to be readable no matter what the 
model transformation is.   With raw OpenGL I used to do something like 
this (I don't have the original code):

glXUseXFont( ... );
glRasterPos3xv(xyz_pos);
glListBase(...)
glCallLists(....,string_to_draw);

Thanks,

     Wayne
