sure all brush effect you describe is possible with the current version BUT you have to learn ( perhaps ) shader coding for that.
My advice ( if you want to ) is to start with more simple samples like varying the color of the brush.
See how the code is made with current default brushes pick a simple one and try to play with it
I am an industrial automation programmer (machine vision, industrial robots, etc. Lots of Pascal-type languages).
Would the best approach be to look at the blur code and the scatter-smudge code to come up with a child of the two?
