A common use case in functional neuroimaging is to overlay multiple statistical maps (with different colour schemes thresholds) over a structural volume/surface. This is quite tricky to do in XTK since one has to use the API designed for a label map and support for multiple layers and continuos and independent thresholding of layers is limited. For an example (but incomplete) implementation see http://braingl.de/
