      40             :             visualisation. This can be (and is) used e.g. for generic shadow
      41             :             visualisation by forcing all color usages of the contained
      42             :             sub-content to the shadow color.

      46             :             processing there is tooling in basegfx to build a stack of
      47             :             BColorModifierSharedPtrs to always be able to process the correct
