Sphere resolution fix filter
From Eclat-Digital Ocean 2014 Documentation
Description
This filter fixes the high noise level caused by the equirectangular projection at the upper and lower parts of spherical renders. The image is filtered anisotropically following the pixel/solid angle projection differential. This ensure uniform resolution and noise levels when projected back on a sphere.
