Summary

Add APIs to configure the step repeat timing for Spinner control.

Problem

The duration that the mouse has to be pressed on a Spinner control arrow button before the value steps is set to 750ms with no way for an application to alter this timing.

Solution

Introduce two new properties initialDelay and repeatDelay, along with APIs to configure these properties. The new properties can be styled with CSS.

Specification

/**
* The duration that the mouse has to be pressed on an arrow button 
* before the next value steps. Successive step duration is set using 
* {@link #repeatDelayProperty() repeat delay}.

* @defaultValue 300ms
