* Preemptive Frames: input_poll and input_state improvements - Check pointing devices when used by core; ignore input_libretro_device - Use stored mouse x,y input state (lower level call might flush deltas) - Remove port mapping code (unnecessary now) - Fewer memsets * Add Preemptive Frames to Qt options menu
