2664  * <pre>
2665  * You may only fire items that "match" your missile launcher.
2666  *
2667  * You must use slings + pebbles/shots, bows + arrows, xbows + bolts.
2668  *
2669  * See "calc_bonuses()" for more calculations and such.
2670  *
2671  * Note that "firing" a missile is MUCH better than "throwing" it.
2672  *
2673  * Note: "unseen" monsters are very hard to hit.
2674  *
2675  * Objects are more likely to break if they "attempt" to hit a monster.
2676  *
2677  * Rangers (with Bows) and Anyone (with "Extra Shots") get extra shots.
2678  *
2679  * The "extra shot" code works by decreasing the amount of energy
2680  * required to make each shot, spreading the shots out over time.
2681  *
2682  * Note that when firing missiles, the launcher multiplier is applied
2683  * after all the bonuses are added in, making multipliers very useful.
2684  *
2685  * Note that Bows of "Extra Might" get extra range and an extra bonus
2686  * for the damage multiplier.
2687  *
2688  * Note that Bows of "Extra Shots" give an extra shot.
