+
+       Direct Start/EndCOlor is no longer required, instead the
+       full color gradient is handed over as ColorStops vector.
+       To add the former Start/EndColor in a compatible way, just
+       prepare an instance of basegfx::BColorStops with the
+       StartColor at 0.0 and the EndColor at 1.0.
+
+       A rigid correction/input data will be done by the constructor,
+       including to sort the ColorStops by offset and removing invalid
+       entries (see sortAndCorrect)
+
+       To access e.g. the StartColor, use getColorStops().front(), and
+       getColorStops().back(), accordingly, for EndColor. The existence
+       of at least one entry is guaranteed, so no need to check before
+       accessing using of front()/back() calls. If only one color entry
+       exists, start == end color is assumed, so not really a gradient
+       but (existing) fallbacks to filled polygon can trigger.
