Remarks
The TrackFill property lets you customize the tracker. The tracker is the splitter ghost image the user sees while dragging. By default, it uses the system select color. However, you can customize it to any color or gradient made possible by SRP's Color Fill technology.
The tracker is always displayed at 50% translucency which cannot be customized.
