Quick test version: (warning: based on first 4.0 beta)

- files must be named <overlay name>_x_led.png> where x = power,df0,df1,df2,df3
- d3d11 mode only
- does not discard transparent space around the leds = wastes memory and GPU bandwidth.
Uses normal alphablending, semitransparent pixels also work as expected.
