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

[Bill Lorensen]

I made a small c++include file that included the class names you said you
use.
Then I ran Utilities/Maintenance/WhatModulesVTK.py on that file.

When you configure your app, try.
find_package(VTK COMPONENTS
  vtkCommonCore
  vtkCommonDataModel
  vtkIOImage
  vtkImagingCore
  vtkInteractionWidgets
  vtkRenderingAnnotation
  vtkRenderingCore
  vtkRenderingOpenGL
)

This does not include Java stuff. You'll need to add that.
