[vtkusers] Speeding up id rendering

Rendering ids (point numbering labels) (500 and up) is very slow. A while
ago I prompted Will about this and he replied as follows:
"The problem appears to be OpenGL. The rendering of fonts is excruciatingly
slow. We've added several optimizations into the code, but it's still
slower than we'd like.
There's rumor that at least one developer has modified the object so that
it spits out "poly data" using something like vtkVectorText. He claims
massive speed improvements."
Is there a method to speed up rendering of ids? What is the identity of the
'one developer' mentioned by Will?
Thanks in advance, Louis
