/**
 * TSlider class
 *
 * TSlider displays a slider for numeric input purpose. A slider consists of a 'track',
 * which define the range of possible value, and a 'handle' which can slide on the track, to select
 * a value in the range. The track can be either Horizontal or Vertical, depending of the {@link SetDirection Direction}
 * property. By default, it's horizontal.
 *
 * The range boundaries are defined by {@link SetMinValue MinValue} and {@link SetMaxValue MaxValue} properties.
 * The default range is from 0 to 100.
 * The {@link SetStepSize StepSize} property can be used to define the step between 2 values inside the range.
 * Notice that this step will be recomputed if there is more than 200 values between the range boundaries.
 * You can also provide the allowed values by setting the {@link SetValues Values} array.
 *
 * A 'Progress Indicator' can be displayed within the track with the {@link SetProgressIndicator ProgressIndicator} property.
 *
 * The TSlider control can be easily customized using CssClasses. You can provide your own css file, using the
 * {@link SetCssUrl CssUrl} property.
 * The css class for TSlider can be set by the {@link setCssClass CssClass} property. Default value is "Slider HorizontalSlider"
 * for an horizontal slider, and "Slider VerticalSlider" for a vertical one.
 *
 * If {@link SetAutoPostBack AutoPostBack} property is true, postback is sent as soon as the value changed.
 *
 * TSlider raises the {@link onValueChanged} event when the value of the slider has changed during postback.
 *
 * You can also attach ClientSide javascript events handler to the slider :
 * - ClientSide.onSlide is called when the handle is slided on the track. You can get the current value in the value
 * javascript variable. You can use this event to update on client side a label with the current value
 * - ClientSide.onChange is called when the slider value has changed (at the end of a move).
