Simon has actually explained this quite well already. The outline you
are stroking is the selection border. Since the selection is a mask it
consists of pixels. So the selection border runs along pixel edges and
thus consists of only horizontal and vertical segments. Zoom in and look
at the marching ants. Now if you stroke this, you get the expected
Stroking with the paint tool is implemented by stamping the brush in
regular intervals along the path you are stroking. This eliminates the
problem somewhat as the stroking does not closely follow the selection
border on its way along the pixel edges.
