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.
Previously using a Pixel Perfect check didn't work if the Sprite was rotated or had a non-zero anchor point, now works under all conditions + atlas frames.
