/**
* 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 <b>step</b> 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.
- *
- * The handle sub-properties can be accessed by {@link GetHandle Handle} property. You can also provide your own control
- * for the handle, using {@link SetHandleClass HandleClass} property. Note that this class must be a subclass of
- * {@link TSliderHandle}
- *
- * 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. Defaults values are "hslider" for
- * an Horizontal slider, or "vslider" for a Vertical one.
- * The css class for the Handle can be set by the <b>Handle.CssClass</b> subproperty. Defaults is "handle", which just
- * draw a red block as a cursor. 'handle-image' css class is also provided for your convenience, which display an image
- * as the handle.
- *
- * 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 <b>value</b>
- * 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).
