LanczosResample

class LanczosResample extends CubicResample

Implemented exactly as in: http://en.wikipedia.org/wiki/Lanczos_resampling#Multidimensional_interpolation

GDAL uses a Lanczos resample radius, *a*, as 3, so our cubic size here is 6 * 6.

This falls back to the Bilinear resample when all 6 * 6 points can't be established.
