[vtkusers] Variable transparancy on vtkImageData

[Mark Gooding]

It appears as Charlotte suggested that vtkImageMapToWindowLevelColors
doesn't like using transparency, so the solution I'm using is
vtkImageMapToColors together with a vtkWindowLevelLookupTable to
acheive both window/leveling and transparency lookup.

Many tThanks to Miguel and Charlotte.
