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.
On Linux, rawpad button array doesn't get populated with GamepadButton objects, so I made a check to verify if it is an object or a number, then pass the correct value to appropriate function.
Also, uncommented the axischange lines.
checkPointerDown method was a verbatim duplication of checkPointerOver - added pointer.isDown check to passed pointer and altered wording of associated docs to make it clearer what the method is doing.
Keyboard.pressEvent stores the most recent DOM keypress event.
Keyboard.processKeyDown now runs the callback after all the objects have been created and/or updated.
Keyboard.processKeyUp now runs the callback after all the objects have been created and/or updated.
Phaser.Keyboard.lastChar will return the string value of the last key pressed.
Phaser.Keyboard.lastKey will return the most recently pressed Key object.
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.
InputHandler._setHandCursor private var wasn't properly set, meaning the hand cursor could sometimes remain (during destroy sequence for example)
All Game Objects have a new property: destroyPhase (boolean) which is true if the object is in the process of being destroyed, otherwise false.
The PIXI.AbstractFilter is now included in the Phaser Pixi build by default, allowing for easier use of external Pixi Filters.
Keyboard.reset has a new `hard` parameter which controls the severity of the reset. A soft reset doesn't remove any callbacks or event listeners.
Key.reset has a new `hard` parameter which controls the severity of the reset. A soft reset doesn't remove any callbacks or event listeners.
