[vtkusers] vtkImagePlaneWidget and RGB colors

[Patrick (Peng) Cheng]

Hi
I am trying to use this widget to display a RGB image (unsigned char, 3 components).
But it can only map the first component. It doesn't treat the RGB voxel as colors.
I look into the code, it seems it's using a vtkImageMapToColors as a build in filter, which might be the problem.
When I use a vtkCutter and vtkPolyDataMapper, it can display the RGB image right.
Anyone knows how to solve this problem?
Thanks a lot!
