Leandro Ribeiro 80d97db856 color-lcms: changes to the parameters of translate_curve_element()
Not a behavior change, but this allow us to decide what function pointer
to use within this function (instead of forcing callers to decide that).

In the following commits this will be helpful. We'll add more curves
besides 3x1D LUT's and, depending on the curve, the function pointer
signature may differ.

Also, we now pass the xform directly to the function, and it can select
the curves depending if it is being called for a pre or a post curve.
