* Generates an 'outline' for a paint device. It should look a bit like the outline of a

|
|
* marching ants selection. You can use it to paint the outline of a KisBrush while painting.
|

|
|
* It's not really optimized, so it's not recommended to do big things with it and expect
|
||
|
|
* it to be fast.
|
||
|
|
* Usage: construct a KisBoundary, and then run a generateBoundary(w, h) on it. After that,
|
||
|
|
* you can use the KisBoundaryPainter::paint method to let it paint the outline, or get a pixmap.
