2690  * You may only fire items that "match" your missile launcher.
2691  *
2692  * You must use slings + pebbles/shots, bows + arrows, xbows + bolts.
2693  *
2694  * See "calc_bonuses()" for more calculations and such.
2695  *
2696  * Note that "firing" a missile is MUCH better than "throwing" it.
2697  *
2698  * Note: "unseen" monsters are very hard to hit.
2699  *
2700  * Objects are more likely to break if they "attempt" to hit a monster.
2701  *
2702  * Rangers (with Bows) and Anyone (with "Extra Shots") get extra shots.
2703  *
2704  * The "extra shot" code works by decreasing the amount of energy
2705  * required to make each shot, spreading the shots out over time.
2706  *
2707  * Note that when firing missiles, the launcher multiplier is applied
2708  * after all the bonuses are added in, making multipliers very useful.
2709  *
2710  * Note that Bows of "Extra Might" get extra range and an extra bonus
2711  * for the damage multiplier.
2712  *
