80fd0d6874 EEVEE: change Glass BSDF behaviour to match Cycles 
changes include:
* Use microfacet normal instead of macronormal. Previously Cycles used
macronormal for Glass BSDF and Transmission component in Principeld
BSDF, leading to velvet-like artefacts at grazing angles. This has been
corrected in 5f9b518a8b and 89218b66c2. Now change EEVEE to match this
behaviour.
* GGX distribution is now darker due to the shadowing-masking term,
while Multiscatter GGX preserves energy as before. This now matches
Cycles too.

Thanks! It does match cycles better. Be sure to update with the latest changes to the Principled BSDF in cycles.
