Updated Predefined Brush engine

[David Revoy]

Hi Dmitry,

Good work ! I launched a first series of test on my preset, and I saw a
regression

It affect preset a bit complex : using Smudge Brush + a Gih animated
Predefined Brush + Dulling
The bug happen at 100% pressure ( can be done with mouse too ) , and I
think it replace the brush tip with a bugged graphism with a lot of noise
in it. It also affect other Predefined Brush here, if I select another
brush mask.

To test, the preset name is 'Bristtle Soft' on this new kit I'm building
for my V3 :

I'll continue to investigate around it
