InputHandler.dragStopBlocksInputUp is a boolean that allows you to control what happens with the input events. If false (the default) then both the onInputUp and onDragStop events will get dispatched when a Sprite stops being dragged. If true then only the onDragStop event is dispatched, and the onInputUp is skipped.

 * InputHandler.dragTimeThreshold gives you more fine control over when a Sprite Drag event will start. It allows you to specify a time, in ms that the pointer must have been held down for, before the drag will begin.
 * InputHandler.downPoint is a new Point object that contains the coordinates of the Pointer when it was first pressed down on the Sprite.
 * There are two new Phaser consts available, for help with orientation of games or Game Objects. They are `Phaser.HORIZONTAL`, `Phaser.VERTICAL`, `Phaser.LANDSCAPE` and `Phaser.PORTRAIT`.
