Problem Statement

Allow easily user modified color gradients.

The inspiration in this case was as a tool for XAML studio, where a user might want to modify a LinearGradientBrush, but it could also apply for art or image editing software.

Overview

This experiment adds a new GradientSlider control and a GradientSliderThumb for the gradient stops inside the slider.
