Weizhen Huang 01fd268921 Fix: Render: Wrong thin glass roughness mapping 
The original mapping from Kulla applies on perceptual roughness instead
of alpha. After this fix, thin glass with low IOR matches the thick
glass better.

Also rename `roughness` to `alpha` in Cycles where it refers to the
`alpha` parameter in GGX for clarity.
