[vtkusers] forward projection, vtkDividingCubes and vtkGaussianSplatter problems

[Lisa Sobierajski Avila]

Hello Zeger,

What are you trying to do? If you are trying to render a volume, you can 
use vtkVolumeRayCastMapper or vtkVolumeTextureMapper2D. Or, if you have a 
VolumePro board from RTViz, you can use the vtkVolumeProMapper. The 
vtkGaussianSplatter is not an implementation of splatting for volume rendering.
