BUG: #3270 Slice Model is white in FA mode

Color scalar image modes were being treated differently with respect
to the image pipeline, meaning that the resulting texture image data was
5 component with a duplicated alpha channel (so it was RGBAA not RGBA).
Putting adding the ExtractComponents instance to the pipeline
took care of this.
