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