Currently, (in the new lib/interpolated.c) Gnuastro does a non-parametric interpolation (median value of a given number of nearest non-blank values). Non-parametric interpolation is very useful to avoid bad fits and impose the minimal assumptions on the result. So currently it is the preferred/only way in Gnuastro.

GSL's 1D interpolation functions were added in commit 1a9147554515.
We still need to add its 2D interpolation functions.
