Footprint algorithms: in the stamp, or in the paintop?

[Emanuele Tamponi]

Ah I forgot the painterly paintop example:

KisBidiOp::paintAt(info)
{
    stamp = currManipulator->createStamp(stampObject,colorSource,info);

    ... alterate stamp using colors on the canvas and viceversa: do the bidi!

    bitBlt(stamp to canvasDevice);
}
