Predefined mask generator biggest time usage is the method Qpainter::drawImage from Qt
However diggging into the method seems to have a SIMD implementation.
The plan for this task is as follows
- Refactor generateMaskAndApplyMaskOrCreateDab to avoid conditions inside loops
- Make a version of transform to work from loaded QImage to KisFixedPaintDevice
- Create optimze vectorize version of implemented transform.
