1. Set jcrop to use a large image, with scaling
2. set the selection coordinates to a region in the image
3. read back the selection coordinates
The expected output is to get back the same coordinates as those originally set.
The actual output is that the returned coordinates vary by a few pixels in many
cases.
I've identified this line in flipcoords() as the cause:
return [Math.round(xa), Math.round(ya), Math.round(xb), Math.round(yb)];
The rounding is performed *before* the coordinates are unscaled, so the extra
detail is lost before multiplying back up to full scale.
This bug also highlights that the width and height values are calculated before
unscaling also, which could lead to similar discrepancies.
