[vtkusers] Glyph sized to a specific number of Pixels

[Ben Held]

Hello,

I would like to display a sphere that is always drawn as a fixed number of
pixels regardless of how far the user "zooms in".  I can display spheres
using standard glyph methods using vtkSphereSource, but the size is fixed to
some physical value.  How do I force it to be a certain number of pixels?

Thanks,

Ben
