I think I've managed to guess what the 16 pixels used for bicubic filtering
are (and the bilinear ones).
Bilinear
x
x*x
x
Bicubic
x x x
xxx
xx*xx
xxx
x x x
The '*' is the pixel being found and the 'x'es are reference pixels. The
outermost pixels are just control points to help align the curve. I _think_
this is correct, but if I am not, please correct me.
