2576  * <pre>
2577  * You may only fire items that "match" your missile launcher.
2578  *
2579  * You must use slings + pebbles/shots, bows + arrows, xbows + bolts.
2580  *
2581  * See "calc_bonuses()" for more calculations and such.
2582  *
2583  * Note that "firing" a missile is MUCH better than "throwing" it.
2584  *
2585  * Note: "unseen" monsters are very hard to hit.
2586  *
2587  * Objects are more likely to break if they "attempt" to hit a monster.
2588  *
2589  * Rangers (with Bows) and Anyone (with "Extra Shots") get extra shots.
2590  *
2591  * The "extra shot" code works by decreasing the amount of energy
2592  * required to make each shot, spreading the shots out over time.
2593  *
2594  * Note that when firing missiles, the launcher multiplier is applied
2595  * after all the bonuses are added in, making multipliers very useful.
2596  *
2597  * Note that Bows of "Extra Might" get extra range and an extra bonus
2598  * for the damage multiplier.
2599  *
2600  * Note that Bows of "Extra Shots" give an extra shot.
