9.3.21: `interpolate'

interpolate x grid to .left. .right. .inc.|{/.cols.}'
interpolate y grid to .bottom. .top. .inc.|{/.rows.}'

Transform grid by interpolating between existing grid data, according to a new x or y grid specified in the manner of `set x grid' and `set y grid'. Note that the new grid is neccessarily regular, while the first grid needn't have been. The data of the new grid are constructed by interpolation, using the same interpolation algorithm as the `convert grid to image' command.
