Summary	0014838: vtkImageMapToColors seems not to handle the output info
Description	Basically I use the pipeline vtkImageCanvasSource2D -> vtkImageMapToColors -> vtkImageViewer2. If I visualize the canvas, without passing through the vtkImageMapToColors filter, everything works fine. If I pass through the vtkImageMapToColors filter, I get a blank render window and the error message : “vtkTrivialProducer (00F15A08) : This data object does not contain the requested extent.” I printed out the vtkInformation objects of the canvas’ output port and the the vtkImageMapToColors’ input port, and both outputs showed the correct extents for WHOLE_EXTENT and UPDATE_EXTENT, but wrong values for COMBINED_UPDATE_EXTENT. Moreover, canvas->GetOutput()->Print() gives also the right extents, whereas the output of the the vtkImageMapToColors shows that basically no meta information has been transmitted. A sample code to reproduce the behavior is attached. I used a vtk git snapshot from 2014-03-02, Windows 7, VisualStudio 2008 32 bit.
