// Strife's FLOATSPEED is 5 and not 4.

// In P_CheckMissileRange, mobjtypes 53,54,55,56,57,58 shift the distance right 4 bits (some, but not all the acolytes)
//						   mobjtypes 61,63,91 shift it right 1 bit
//
// When shooting missiles at something, if MF_SHADOW is set, the angle is adjusted with the formula:
//		angle += pr_spawnmissile.Random2() << 21
// When MF_STRIFEx4000000 is set, the angle is adjusted similarly:
//		angle += pr_spawnmissile.Random2() << 22
// Note that these numbers are different from those used by all the other Doom engine games.
