I'm not sure it was about the exact type of JAI operation used. I don't think 
that JAI itself was failing. If I remember right, it was about the destination 
image not meeting the conditions for which an AffineTransform "gridToCRS" has 
been computed, and this was generally occuring after some kind of affine 
operation. But again we would need to try for being sure.

The bottom line is that if we computed a "gridToCRS" transform for an image 100 
pixels width and we got an image 101 pixel widths because of the rounding error 
described in GeneralGridRange javadoc, that "gridToCRS" transform is wrong. Not 
completly wrong, but a 10 km error can be a lot for some computation purpose.
