[WiiFlash] improving IR mapping

[Usman "Ozzy" Farman]

It seems to me that the field of view of the wiimote is a little less on 
the horizontal axis if you are close to the sensor bar, move the bar 
further away from you and it should ease up, also, if its really jumpy 
be sure to turn off any incandescent bulbs around... took me a while to 
figure that out. :)
