[vtkusers] Minimizing VTK footprint (Java Web Start application)

[Marco Sambin]

Hi Bill,

thanks a lot for your suggestion, which confirmed that the subset of VTK
libs that I identified was really the minimum possible subset considering
the VTK classes I am using (maybe I can remove just vtkViewsCore - still
need to check - but in any case it takes just a few KBs).

Is there really no other way to further reduce this footprint?

Thanks and best regards,

Marco Sambin
