// Transform takes a ColourScheme, a ViewRegionMap and a viewport as input.

// and any ViewRegions outside of this area are not forwarded for further processing.

// The remaining ViewRegions are then passed on to the ColourScheme for determining the exact Flavour
// for which that RegionSet should be styled, adding Regions of the same Flavour to the same RegionSet.

// a ColourScheme, so this operation can be viewed as reducing the number of state changes required to
