!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
rspl now supports different resolution grids in each dimension.
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
This is the second generation Regular Spline library.
It contains scattered data point to regular grid interpolation,
as well as spline smoothing, and the reverse interpolation
code. This version is more modular, and uses better solution
algorithms than the earlier REGSPL, and generally replaces it.
The reverse interpolation algorithms support features needed
for devices like CMYK printers, such as total ink limiting,
black locus selection, gamut boundary detection, vector
and nearest gamut clipping.
It has been written with operation with 6 color printing
devices in mind (ie. 3 extra degrees of freedom, and hence
a 3 dimensional inking locus), although this usage is likely
to be unwealdy.
