missile size excessive

[QuakeIV]

It looks like missile size is scaled on every dimension by the number of missiles launched.  This has unfortunate side effects, such as the following with large launchers:



This isn't really a bug per se, since it seems to work fine, but I suggest scaling the missile by the cube root of the number of missiles launched, as that is more mathematically/volumetrically correct and will limit how often this kind of thing happens.
