Rain Related Console Commands

There are a number of console commands that control func_precipitation rendering. These include: r_rainalpha, r_rainalphapow, r_raindensity, r_rainlength, r_RainHack, r_rainlength, r_RainProfile (displays stats on rain rendering costs), r_RainRadius, r_RainSideVel (controls sideways movement of the rain particles, e.g. to simulate rain in the wind), r_RainSimulate (toggles animation on the rain; freezes the rain when set to 0), r_rainspeed, r_RainSplashPercentage and r_rainwidth.

Todo: The names of these seem descriptive enough for most of them, but what do r_rainalphapow and r_RainHack do?
