This implements an update to the look of the Slider widget. Specifically, it does the following: * Adds the ability to customize the colors of all components of the slider * Adds the ability to customize the shape of the slider thumb and value indicator * Adds the ability to show the value indicator on continuous sliders * Updates the default value indicator to be a "paddle" shape with new animations. * Changes the tick marks to be visible all the time on discrete sliders * Fixes a memory leak of an animation controller. * Removes "thumbOpenAtMin" flag, which is no longer needed, and can be emulated by the custom thumb shape support. It was not widely used. * Adds tests for all of the new features.
