* Wind updates. Still random.. but in 4 directions instead of two!

Browse Source 
* It seems kind of silly to be building a 256x256 array just to use two 16 float blocks..  but for now the layerdata routine requires it so we'll go along with that.
* We only fill a 32x16 area of the 256x256 float array with data.
* We use patches 0,0 and 0,1 for the first and second patch to determine the direction and magnitude of the wind.
