be able to comb hair also after a hair physics emulation.

Currently when combing hair, this happens before hair physics, it would be handy if hair could be brushed later in time as well.. Perhaps internally handle it as multiple hairbakes.

The new hair positions could be smoothed over x frames before.

This would help to solve situation where after a physics symulation some hairs endup in strange positions and need to be fine tuned, fine tuning is currently not possible.

After the combing new physic bakes if wanted should be possible,

Another way to think of it is maybe a corrective hair brush.
