Allow parallelisation of masks (#636)

Quellcode durchsuchen 
* Allow parallelisation of masks
Increasing performance improvement with increased masking complexity and edit size.

* Address comments
 - Rename Mask#clone to Mask#copy
 - Rename Mask2D#copy to Mask2D#copy2D
 - Correct formatting

* cx -> centerX

* Make various operations relying on a single SingleThreadQueueExtent instance (mainly brushes) thread safe
