  37
  38             This primitive is a grouping primitive and allows to define
  39             how the colors of its child content shall be modified for
  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.
  43
  44             For the possibilities of color modifications, please refer
  45             to the basegfx::BColorModifier definitions in basegfx. For
  46             processing there is tooling in basegfx to build a stack of
  47             BColorModifierSharedPtrs to always be able to process the correct
  48             colors.
  49
  50             If a renderer does not handle this primitive, the content will
  51             be visualized unchanged.
