New color blending

[JoseConseco]

Hi, I saw new Borodante video about AS Pro 2.2 and new average blending looks great.
I remember he mentioned it is going bit slow for big brushes (600px) even with metal support.
I wonder are you using subsampling for color blending? Maybe this can bump the performance without visual quality loos. 
There is one cool doc about it: http://extremelearning.com.au/evenly-distributing-points-in-a-triangle/
Picking 100points, vs 600x600 points should provide speed boost right (I assume this is the most time consuming part).

It is already optimized, believe me

Where is it? It's neither in layers nor in brush settings.

Go to Brush Editor, Wetness, and move Blur Radius slider to the max
It is used in Juliano Oil Texture brush (Wet Paint tool)
