[vtkusers] BUG IN vtkImageReslice

[David Gobbi]

Hi Gerald,

Multi-component reslicing is part of the regression tests:

VTK/Imaging/Testing/Tcl/ResliceColorWrap.tcl

Remember that you have to call Update() on reslice or on its output
before you can call
reslice->GetOutput()->GetNumberOfScalarComponents().  The information
is not updated until either Update() or UpdateInformation() is called.
