Use column for filter/color but not for projection

[ch-sander]

My data has clusters that are precalculated and hence should not impact the projection but would remain useful for color coding and filter. I cannot include them for the latter without using them for the projections.

Also, columns not used for the projection should still be usable in the tooltips
