示例1: decorateRect

KisSafeFilterConfigurationSP filterConfig = filter();

"src must be != dst, because we cant create transactions "
"during merge, as it breaks reentrancy");

* FIXME: try to cache filter pointer inside a Private block

* FIXME: This check of the emptiness should be done

* We can't paint outside a selection, that is why we call
* KisMask::changeRect to crop actual change area in the end
*/

* FIXME: Think over this solution
* Union of rects means that changeRect returns NOT the rect
* changed by this very layer, but an accumulated rect changed

* documentation accordingly
