Brecht Van Lommel 44be56fd49 Cycles: Smoothly blend denoising features to avoid artifacts
Albedo and normal denoising features passes used several hard cutoffs
that lead to discontinuities in the passes and sometimes the denoised
render too. Use smooth transitions instead.

Specular roughness cutoff of 0.075 replaced by a smoothstep from 0.0
to 0.15. Specular and transparent 25% threshold replaced by diffuse to
specular ratio blend from 0.0 to 0.5.

Also stop using sample_weight which is meant for importance sampling
only.
