Gradient fill-element

This class is used throughout Image_Graph to perform gradient fills. It is mainly used for diagram-data-elements (like a bar or a line) and the diagram-grid. Note that also more than 2 colors can be provided which will result in a gradient-fill from one color to the next [...] to the last one (multiple gradients).
