+    /** base class to define color modifications
+
+        The basic idea is to have instances of color modifiers where each
+        of these can be asked to get a modified version of a color. This
+        can be as easy as to return a fixed color, but may also do any
+        other computation based on the given source color and the local
+        algorithm to apply.
+
+        This base implementation defines the abstract base class. Every
+        derivation offers another color blending effect, when needed with
+        parameters for that blending defined as members.
+
+        As long as aw080 is not applied, an operator== is needed to implement
+        the operator== of the primitive based on this instances.
+
+        For the exact definitions of the color blending applied refer to the
+        implementation of the method getModifiedColor
+
+        BColorModifier is not copyable (no copy constructor, no assignment
+        operator); local values cannot be changed after construction. The
+        instances are cheap and the idea is to create them on demand. To
+        be able to reuse these as much as possible, a define for a
+        std::shared_ptr named BColorModifierSharedPtr exists below.
+        All usages should handle instances of BColorModifier encapsulated

+            just return itself.
+
+            The subdivision is created on first request and buffered, so when using

+            to accomplish on bezier segments (e.g. isInEpsilonRange).
+
+            The current default subdivision uses adaptiveSubdivideByCount with 9
+            subdivisions which gives 10 edges and 11 points per segment and is
+            usually pretty usable for processing purposes. There is no parameter

+            between the different kinds of subdivisioned and passing them one
+            parameter.
+
+            The lifetime of the buffered subdivision is based on polygon changes.
+            When changing the polygon, it will be flushed. It is buffered at the
+            refcounted implementation class, so it will survive copy by value and
+            combinations in PolyPolygons.

+            (b) the range of the polygon points and control points
+            (c) the outer range of the subdivided bezier curve
+
+            Ranges (a) and (c) are produced by tools::getRange(); resp. this
+            getB2DRange(). tools::getRangeWithControlPoints handles case (b).
+
+            To get range (c) a simple solution would be to subdivide the polygon
+            and use getRange() on it. Since subdivision is expensive and decreases
+            the polygon quality, i added this new method. It will use a
+            methodology suggested by HDU. First, it gets the range (a).
+            Then it iterates over the bezier segments and for each it
+            first tests if the outer range of the bezier segment is already
+            contained in the result range.
+
+            The subdivision itself uses getAllExtremumPositions() to only
+            calculate extremum points and to expand the result accordingly.
+            Thus it calculates maximal four extremum points on the bezier
+            segment, no split is used at all.

+            It is now capable of keeping contained bezier segments.
+            It is also capable of delivering line and non-line portions
+            depending on what target polygons You provide. This is useful
+            e.g. for dashed lines with two colors.
+            If the last and the first snippet in one of the results have
+            a common start/end ppoint, they will be merged to achieve as
+            view as needed result line snippets. This is also relevant for
+            further processing the results.

+            The line pattern given as array of length values
+
+            @param pLineTarget
+            The target for line snippets, e.g. the first entry will be
+            a line segment with length rDotDashArray[0]. The given
+            polygon will be emptied as preparation.
+
+            @param pGapTarget
+            The target for gap snippets, e.g. the first entry will be
+            a line segment with length rDotDashArray[1]. The given

+

+            functions that get called when a snippet of a line/gap is
+            produced and needs to be added. This allows to use it like
+            a 'pipeline'. When using this (e.g. the 1st version uses
+            this internally to guarantee the same algorithm is used)
+            it is not needed to accumulate a potentially huge number
+            of polygons in the result-polyPolygons, but e.g. consume
+            them directly in the caller. Example is rendering a
+            dashed line but without creating the potentially huge amount
+            of polygons.
+            The 2nd version will also merge first/last line/gap snippets
+            if the input polygon is closed and the start/end-points match
+            accordingly - at the cost that this will be delivered last.

+

+
+        That means, isInside(val) will return true also for values of

+
+        Alternatively, consider this a rectangle, where the rightmost

+        is much like polygon filling. As a result, filling a given

+            bound rect in a given direction.
+
+            This method is useful when e.g. generating one-dimensional
+            gradients, such as linear or axial gradients: those
+            gradients vary only in one direction, the other has
+            constant color. Most of the time, those gradients extends
+            infinitely in the direction with the constant color, but
+            practically, one always has a limiting bound rect into
+            which the gradient is painted. The method at hand now
+            extends a given parallelogram (e.g. the transformed
+            bounding box of a gradient) virtually into infinity to the
+            top and to the bottom (i.e. normal to the line io_rLeftTop
+            io_rRightTop), such that the given rectangle is guaranteed
+            to be covered in that direction.
+
+            @attention There might be some peculiarities with this
+            method, that might limit its usage to the described
+            gradients. One of them is the fact that when determining
+            how far the parallelogram has to be extended to the top or
+            the bottom, the upper and lower border are assumed to be
+            infinite lines.

+            when determining the extension direction. Thus, it's
+            perfectly legal to affine-transform a rectangle, and given
+            the transformed point here. On method return, this
+            parameter will contain the adapted output.
+
+            @param io_rLeftBottom
