* Adds some Wind
* A little wind wouldn't hurt anyone, right? This is the 'slightly breezy' setting.. hopefully you won't notice 'much' of a difference. * It turns out the terrain patch routine is similar enough to the wind version that it can be used to hack together a breeze generator with a few mods. * Not much configuration.. yet. You only get breeze updates in the general vicinity of your camera now to keep bandwidth usage down.. and we're not talking about 'much' movement at the moment. * initial version... could use improvement I'm sure.
