Description

From a comment by @XianXing on PR #131:

"The computation and approximation for Hessian diagonal was designed and implemented independent of Photon's normalization, because previously we didn't enable normalization for GLMix.

But it will be helpful if we take the normalization into account as well here for Hessian diagonal, in order to make it consistent with the rest of code."
