CoronaRoundEdges possible bug

[romullus]

Rounded corners should occur on hard edges only, if i understand it correctly. However it seems that's not exactly how it happens in Corona. It looks that it appears everywhere if you look for it hard enough. In attached pictures, spheres has same material with round edges and mapped round radius, only difference that first sphere has disabled smoothing and second one  has one smoothing group. Red dot shows rounded radius. I deliberately exaggerated effect to show problem. It doesn't show at normal bump strength, but you can tell it's there by increased rays/sample. Also it can be clearly observed when displacement is involved.

it works differently, it detects any change of the surface. We will work on the algorithm in the future to make it better. This is already logged in mantis
