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

	vips copy car-stack-eighth.hdr x.jpg

1bddb78f6a split sRGB <-> XYZ up 
split sRGB <-> XYZ into sRGB <-> scRGB <-> XYZ so we can support
scRGB as a colourspace

77ec00b495 check for NaN etc. in XYZ2sRGB 
we were not checking for Inf, NaN etc. and this could cause array
indexes to go out of range

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)

efcc53859a capture tiff warnings during startup 
We were not capturing warnings from libtiff until we used libtiff
ourselves. Other libraries whcih we call, such as ImageMagick, could use
libtiff and generate an uncaptured warning.

On Windows these warnings each produced a popup.
