Rebuilt the way items are polled for Pointer events (drag, click, move). Now faster and more efficient, especially when some items in the stack require pixel perfect checks.
Pointer.withinGame is now accurate based on game scale and updated as the Pointer moves.
Stage.bounds is now updated if the game canvas offset changes position. Note that it gives the un-scaled game dimensions.
QuadTree.retrieve can now accept either a Sprite with a physics body or a Phaser.Rectangle as its parameter.
ArcadePhysics.getObjectsUnderPointer will return all children from a Group that overlap with the given Pointer.
Input and Pointer now use the new ArrayList instead of a LinkedList, which resolve list item removable during callback issues.
Input.reset no longer resets every interactive item it knows of, because they are removed during the destroy phase and can now persist between States if needed.
World.shutdown now removes all children iteratively, calling destroy on each one, ultimately performing a soft reset of the World.
Objects with a scale.x or y of 0 are no longer considered valid for input (fix#602)
InputHandler will set the browser pointer back to default if destroyed while over (fix#602)
Group.destroy has a new parameter: `soft`. A soft destruction won't remove the Group from its parent or null game references. Default is `false`.
InputHandler.validForInput is a new method that checks if the handler and its owner should be considered for Pointer input handling or not.
Group.replace will now return the old child, the one that was replaced in the Group.
Fixed issue where renderOrderID wasn't being assigned correctly, causing the Input Handler to be unable to select the "top" item on a display list (would all default to zero)
Fixed issue where Stage would assign renderOrderIDs in reverse, should be in sequence.
Fixed issue where objects where checking World for the currentRenderOrderID by mistake instead of Stage.
Basically, input handling works a lot better now for Groups and nested objects :)
Stage.aspectRatio has been moved to StageScaleMode.sourceAspectRatio (so now game.scale.sourceAspectRatio)
Stage.scaleMode has been moved to StageScaleMode.scaleMode (so now game.scale.scaleMode)
Stage.fullScreenScaleMode has been moved to StageScaleMode.fullScreenScaleMode (so now game.scale.fullScreenScaleMode)
Stage.canvas has been removed. It was only ever an alias for Game.canvas anyway, so access it via that instead.
InputHandler.pixelPerfectOver - performs a pixel perfect check to see if any pointer is over the current object (warning: very expensive!)
InputHandler.pixelPerfectClick - performs a pixel perfect check but only when the pointer touches/clicks on the current object.
PLEASE DO NOT upgrade to this release if you need your game working and it uses any of the physics functions, as they're nearly all broken here.
Just pushing up so I can share it with someone.
* Updated: Sprite.deltaX/Y removed due to non-use. prevX/Y values moved to Sprite._cache.prevX/Y.
* Updated: Due to missing extends parameter the Sprite prototype was picking up functions from classes it never meant to (Button, TilemapLayer), now fully isolated.
