I wasn't keen on the fact that the control-point doesn't necessarily  
represent the actual point co-ords and that as a bicubic patch it only  
allows 16 vector points which means dividing the data file into 4x4 'sets'  
<0,0,Y>,<4,0,Y> to <4,0,Y,>, <4,4,Y> etc. and then recreating the patch  
with the correct data 'set' each time. Of course you have to assume the  
data is divisible by 16 or pad it. I must admit with the code here I  
assumed it was square, but that's easily changed.

It seemed to fiddly to do with a bicubic patch, though of course if you  
care to try I'd be interested in seeing your code :)
