app: port GimpBlendTool to pause()/resume()-less drawing 

Instead, keep around the created GimpCanvasItems, and update them when
the blend coordiates change. Add setters to GipmCanvasLine and
GimpCanvasHandle which take care of calling begin_change() and
end_change() on the items around the change, so thes invalidate
properly.
