fixed bug with cutting through laser emitter in special cases in MM engine

While the laser beam can be pointed at the middle of the laser emitter
element, and also can slightly touch it at its very edges, it should
not be possible to cut through it nearer to the middle, but without
really hitting the middle of the laser emitter.
