Thanks Paul,
It is still hard to find any floating point profiles to check, so your
patches are much appreciated. Specially the test code.
Best regards

I've been testing some floating point monitor profiles, and I think I have
found a couple of bugs in the floating point sampled curve support in the
latest lcms
cmsBuildTabulatedCurveFloat builds a curve which always evaluates to 0 for a value of
0. I have changed it to use a constant segment which matches the first sample for
values <= 0, and also added a similar segment matching the last sample for values
> 1.0 (the ICC spec says that the first and last segments in a segmented curve
should be function segments).
EvalSegmentedFN gives the wrong result when evaluating a sampled segment where
x1 - x0 is not 1.0
I have also added tests to testcms.c to verify the changes.
Suggested patches attached....
(apologies if this turns out to be a duplicate: I sent it to the list request
address by mistake)
