A value slider.
Functionality
A slider lets you select a value within a range (min, max), with stepping between each value the slider represents. To listen for changes of the slider value one can register a {@link ValueChangedListener} with the slider.
Layout
A slider's (preferred) width and height are determined by the parameter past to its constructor as well as the maximum height of the {@link NinePatch} and {@link TextureRegion} involved in the display of the slider. Use{@link #setPrefSize(int,int)} to programmatically change the size to your liking. In case the width and height you set are tosmall you will see artifacts.
The slider background will only be stretched in the x-axis. The slider handle will be centered on the background vertically.
Style
A slider is a {@link Widget} displaying a horizontal background {@link NinePatch}, stretched on the x-axis and using the total height of the NinePatch on the y-axis, as well as a TextureRegion for the slider handle. The style is defined via an instance of {@link SliderStyle}, which can be either done programmatically or via a {@link Skin}.
A Slider's style definition in a skin XML file should look like this:
```
 {@code }
```
- The name attribute defines the name of the style which you can later use with {@link Skin#newSlider(String,float,float,float,float,String)}.
- The slider attribute references a {@link NinePatch} by name, to be used as the slider's background
- The knob attribute references a {@link TextureRegion} by name, to be used as the slider's handle
