John Cupitt e6eb08173f can now displace affine input space 
so hopefully that means you can change corner vs. centre convention
easily

John Cupitt c5a600b286 tag Radiance images as scRGB 
They aren't always, but scRGB is also 0-1 range, so conveniently this
now works:

John Cupitt 1aee7b73d5 start new max hacking 2012-12-03 14:53:10 +00:00
John Cupitt 6f22c00df4 NN now rounds down rather than to nearest 
nearest-neighbour interpolation now strictly rounds down rather than
rounding to nearest

round to nearest caused strange half-pixels along top/left image edges
during enlargement, and extra 1.5 sized pixels everywhere else

instead we should fix the thing that round to nearest was supposed to fix by
adding an extra pair of params to the affine transform which displace in
input space (dx/dy displace in output space)
