/** FillGraphicPrimitive2D class
This class defines a bitmap filling for a rectangular area. The
Range is defined by the Transformation, the fill by the FillGraphicAttribute.
There, the fill consists of a Bitmap (not transparent) defining the fill data
and a Point/Vector pair defining the relative position/size [0.0 .. 1.0]
inside the area where the bitmap is positioned. A flag defines then if this
is tiled or not.
Renderers should handle this primitive; it has a geometrically correct
decomposition, but on pixel outputs the areas where the tiled pieces are
aligned tend to show up (one overlapping or empty pixel)
