/** ModifiedColorPrimitive2D class
This primitive is a grouping primitive and allows to define
how the colors of its child content shall be modified for
visualisation. This can be (and is) used e.g. for generic shadow
visualisation by forcing all color usages of the contained
sub-content to the shadow color.
For the possibilities of color modifications, please refer
to the basegfx::BColorModifier definitions in basegfx. For
processing there is tooling in basegfx to build a stack of
BColorModifierSharedPtrs to always be able to process the correct
colors.
If a renderer does not handle this primitive, the content will
be visualized unchanged.
